[@z74birdman]

I like your explanation of headers fitting...yes it was challenging at every turn point. Here is my problem...Someone at hooker headers welded my collector upside down on the drivers side...which left the header stuffed up against the floor board...which requires removing/cutting and rewelding the collector to make it fit...the manifolds are now back on the car permanently...between having to modify my Z bar and rewelding the collector...it just wasn't worth the aggravation for an extra 15 hp.

[@FastMonty]

Going from memory. About 1974 installed Hooker headers on my 66 GTO. Also had issues with oil filter and starter. Other than they fit well on a 389 .060 over, 400 engine. Great headers. Had a 2:20:1 Muncie no issues.

[@bluesman7475]

First thing on a Pontiac, is find out if you are running round port or D port heads. You must match the correct header shape to the head. Second thing is check the heads to be positive the heads have all the bolt holes to put in all the bolts (some 326 and 350 engine heads do not have all the bolt holes). They will have to be drilled and tapped to avoid exhaust leaks. Third, be aware that some items may have to be moved of deleted. On my 74 SD-455 trans am the arm for auto transmission lock when the key was off, had to be deleted. The drivers side was very easy, the passenger side more difficult as I had AC on the car. I did have to remove the oil filter for installation, then run a short vs tall filter after installation. As Monte showed, you make have issues with the factory exhaust pipes lining up with the flanges of the headers. As a KISS guy myself, I ran header mufflers that came with flanges and then added turn downs in the rear. This made the exhaust system exit just in front of the rear axel. That way I did not have to deal with the power robbing sideways muffler on some firebirds and did not have to deal with tailpipe fitting over the axel. In my case, I have used Cyclone, Hedman, Doug Thorley street tubes, Doug's headers and Hooker headers. I have never had an issue with Hookers fitting properly.

That's awesome! Thanks for great, detailed comment!

[@mattspontiacta]

I ran Hooker #4109 headers on my 79 400 4spd trans am. Headers fit perfect. No issues at all with the Z- bar or oil filter. No mods or dimpling of the header primary’s . But had another friend that had almost the same TA that I had. He had to ding some of the header tubes. We figured the headers were made on different jigs at the manufacturer. Who knows.

[@FastMonty]

Yeah, it's crazy how some sets fit fine, and others don't, even from the same manufacturer. Thanks for the comment!

[@v8pontiacvent]

Hooker Headers worked well for me. 1972 Pontiac Ventura II, 350/TH2004R. Can change the oil filter without having to remove the filter housing. Since the oil filter does sit directly above the header, I just put a plastic bag over the header so the oil won't drip on to the header directly when the filter is removed.

[@FastMonty]

Love the tip! Thanks for the comment!

The struggle is real! Nice build... stay with it, be patient, you'll get there. Good luck!

[@stevenlynch6605]

My first set of headers was Headman, so on the oil filter side when I change the oil I just used to cover the header with plastic and spin off the filter. Little messy, but worked. My Doug's headers just came today so next week we going to see what it do.

[@FastMonty]

Thanks Steven, looking forward to the update of your Doug's headers. Have fun!

[@stevenlynch9947]

@@FastMonty I found my header bolts that came with the Doug's headers they are a 1/4 of a inch longer the regular header bolts. Driver side went in easy I was finish in 15 min. The other side is giving me all the problems. My car is a '65 Le Mans , so I might have to trim the A-Arm bracket on this side or tilt the motor.

[@FastMonty]

@@stevenlynch9947 Glad you found the bolts... bummer about the fit, or lack there of. Let us know how you solve it.

[@MidnightinSavannah]

I'm guessing you have aftermarket control arms which probably lowered the front end. I have never had any issues with Hooker Super Comps on any of my 1968-72 A-body headers. Personally, i would have never cut on the frame.

[@FastMonty]

Totally agreed about not hacking the frame. I'll be fixing that hole when I yank the engine next year. Control arms have nothing to do with it... the problem is I had to shim the block higher due to the larger oil pan I'm using. Naturally that raises the headers, hence the issue. I'll check out those Hooker's Thanks!

[@KillerNetDog]

I've had headers back in the day that fit perfectly, it does happen occasionally. Right now I'm putting some Fkowtech headers on a '82 chevy pickup with a 350.. They fit pretty good, but I'll be heating and bending the tubes to move the collector over and up a bit on both sides.

[@FastMonty]

That's awesome! Thanks for the comment!

[@richmargadonna2155]

Hey my friend. I also have a 69 that I bought brand new. It's a Ram Air IV and I can tell you that when I went to put headers on it about 10 years ago, it had me in tears because of the poor fit. Had to relocate the proportioning valve, 2 lower control arm bolts had to be removed and installed the opposite way, and the 4th bolt back on each side is nothing less than impossible. Even on the lift and lifting the engine, the driver's side wouldn't go in no matter what. The left cylinder head had to come off to get the header to lay in the right place. Way too much work... and I spent my whole career in auto repair, so it's not a lack of experience. Admittedly, I bought the headers right after I bought the car and they sat in the box for decades, so the header technology is from 1969. They're Doug's headers which was the only thing available for round port heads way back then. They did have some plusses. Didn't have to remove the oil filter adapter and the filter can easily be removed. The back-drive column lock linkage still works. No problem with the clutch linkage. Caster/ camber adjustments will be a bit tricky but not impossible. All in all I will say this: Unless you seriously intend to race your car where you don't mind laying in the dirt to uncork the headers, then avoid these things like the plague. Buy the free flowing Ram Air exhaust manifolds and be happy with them. If you really need that extra 20-25 HP that headers give you, find it somewhere else in the engine and throw the headers in the trash. If I ever need to remove the heads again, the factory Ram Air IV exhaust manifolds are going back on. At this point in my life, I'm not crawling under the car to undo collectors. I'll use that energy to snap through the gears.

[@FastMonty]

Hey Rich... I LOVE LOVE LOVE this story, and fully agree about getting to old to get under cars, ha, ha... that's why I have a lift now. Anyway, thanks for taking the time to comment, and I wish you well! Thanks again.

[@puddleduckist]

I have a 69 gto as well and have headers. I use the same remflex gaskets on the headers and collectors. To make it easier and look cleaner i trimmed around each port so each one matches the head without xtra metal. I slotted one of the holes so it can be hung in place. I originally had hooker super comps and they hung low and bottomed out. I bought a set of dougs and i have d port heads. One side fit great one hit the frame. Sent them back had a set of mad dog headers made and ended up being for a grand prix. I ended up buying hooker super comps again and trimmed the ports and had then ceramic coated. They fit great although a bit low but not too bad. Headers on a pontiac are no joke and that center bolt is from hell but it's worth it in the end. I'm about to swap out my old torque tech 3 inch exhaust to a new pypes 3 inch stainless with x pipe and i have new pypes race pros.

[@whereisamerica7384]

This isn't criticism, it's 30+years of observation. A lot of fitment issues are not reading the install notes/instructions. The headers were built for a specific set of motor mounts and FRAME MOUNTS. I'm guilty of it too. After changing frame mounts on a 72 chevelle, headers that didn't fit, fit perfect.

[@FastMonty]

Agreed about using stock motor mounts, etc... The "Manual" gearbox doesn't help either. As the headers have to clear the older style clutch Z bar, etc... Now that I have a hydraulic clutch, I might experiment with headers built for "automatics". Thanks!

[@davidsearle6449]

Does those flanges take away some horsepower because they are not straight

[@FastMonty]

Good question David. You mean my diverted collectors? I don't think so... reason is, the flow of exhaust is not uniform, ie not constant, and they're only 45 degree curved bends. I remember seeing an episode on Power Nation, I think? Anyway, they dyno'd headers that were perfect and headers that had dents in it, you know, to fit around the frame... results were the same, because exhaust is in pulses, not constant. So, I'm pretty confident there isn't any loss. Hope that helps... thanks for the comment!

I had to relocate my brake proportioning valve to get mine to fit lol I went with the summit racing headers on my 69 getting them in was a pain but i didn't have to do much to the headers to fit. they did hit the top of cross member of the frame pretty good so i had to get engine fame mount spacers to lift the engine and a few small dents where they hit but i didn't have to do any frame modifications and also spaced the transmission to correct driveshaft angle. the nice thing with these headers is I can remove the oil filter without removing the filter housing. overall not bad for the price and they lined up nicely with the pypes street pro exhaust only had to to cut a notch near the collector bend it up a little and weld it up on the driver side. But I can tell you this if the engine ever has to come out in the near future going to go with a ram air alum exhaust manifold and save me the headache lol

[@FastMonty]

Yeah, certainly was a pain... my next set will be more custom. ha, ha...

[@nashvilleoutlaw]

I disagree about the variations from the original car they used for mockup. I believe manufacturers are just lie and say they will fit an application when they really don't. Hooker sent me 2 sets for my impala and both had the same issue. One tube was routed so far into the passenger tie rod it was almost on the other side of it. On 67 impala's the tie rods are routed behind the cross member under the engine. I had to cut the tube and completely reroute it. It was an all original matching numbers car. I could understand maybe having to put a dent in one in a tight spot from variations in a model. But the only way they could have designed the ones they sent me without having the same trouble I had was if they designed them without the front steering on the car.

hey Monty did you have to get a little longer headers bolts? I'm looking at the standard header bolts and like an inch long and with that thick flange on the Dougs might need inch and a quarter.....

[@FastMonty]

Hmmm, If I'm not mistaken, the bolts came with the headers. Do you have the headers yet?

[@stevenlynch6605]

@@FastMonty yeah I bought mine from Summit I don't recall seeing the bolts just the gaskets. Anyway I think I'm going to get some Black Chrome Molly don't want any rust.

[@heavymetalmadness666]

One thing to keep in mind is how many different motor mount combinations might exist for your makes of cars. Also for anyone running aftermarket heads, you are possibly multiplying fitment issues. I would not cut at or grind on the frame. I've had a hell of a time once on a A-body and after several different mounts found ones that worked. There is play in how the lower motor mount attaches to the frame as well to tilt things around . That's a pain in the ass , but a better solution to butchering things up .Raise the engine a tad or forwards or back a tad with motor mount adjustments. Last support the car as it carries the weight, and what I mean by that is cars bend and twist all around( more so if not true uni-body). I don't consider Camaros a true uni-body until the third generation for an example. Guess what ,when you do everything you can right (unless you have solid motor mounts ) its going to move around a lot running and driving aside from any added frame /sub frame flex. Drive some shaker cars, or just cut a hole in the hood for the air cleaner to stick out through and you will get my point. Based off the distance from the mounting point to the top of the air cleaner the movement is not the same, but exhaust mounts somewhere in the middle of that math equation.

[@FastMonty]

All good points. As I said, cutting the frame is not ideal... the things we do for more power... ha, ha... thanks for the comment!

[@tomlanese3827]

68 GTO w/1973 pontiac 455, 6X d-port heads, 5 speed tremec. I used ceramic coated Hooker super comp 2 headers. Bolted right up with no clearance issues, but they were put in when the frame had no body on it, so it was easy. Rest of car has a dual 3" Torque Tech system with no crossover (This system is all coming out and being replaced with a new Pypes 2.5" and RA manifolds). Looks like the headers have to come out from below. I've been putting off this project for 6 mos. :(

[@FastMonty]

Thanks Tom! I appreciate you sharing your story. I definitely understand the hesitation to start that project... it'll go fine. See ya!

[@frekkledipped]

my gto headers made the inside of the car so hot it was undriveable on a hot day here in Nor Cal, with header wrap be careful they dont get wet they will rust the pipe over time

[@FastMonty]

Thanks Dan, yup, there are consequences for more power. Ha, ha... thanks for the comment!

I have a 75 trans am 400 D-port heads I'm using headman headers shorties and I'm having exhaust leaks everywhere and it's messing with my O2 sensor on my Fitech. I ordered remflex gaskets hopefully they resolve my problems. If not I'm going back to stock manifolds .

[@FastMonty]

Thanks for sharing, David. I understand the frustration... I hope the Remflex gaskets solve the problem, because I too love headers. (I wish they had shorties for my car) Keep us posted!

[@jimreaume2937]

Restoring a 68 Mustang FB, dealing with long headers (Hedman), putting in a custom z-bar, but in the process of mocking up exhaust for running the engine. I have to make sense out of the prior owner's purchase of exhaust tubing - nothing but butt connections and no way right now to attach to the header flange, Good tips here for sure. By the way - what's your camera setup and how do you like that Eagle compressor?

[@FastMonty]

Inheriting someone else's work is never fun. But, the challenge is what makes it worth doing. My Eagle compressor is awesome. I've had it about 10 years. My camera is my cell phone. Crazy huh? Thanks for the comment!

[@How_the_gods_drill]

64 gto with a 400. First time I put a set of hookers on it three hours a special wrench and a ship load of sailor language they are on. Then the rear main leaked. Two hours more taking the headers off never again. Enter Doug's headers fit like a glove a standard 3/8 wrench reaches all the bolts.

[@gregorykern9679]

Ha! Ever install them in a Mopar? Christ....I have a 1970 Charger. Ma Mopar didn't do us ANY favors in terms of clearance. The right side is okay for big block cars. That is a nice thing because the left side is the worst that I have seen in any American car. There is the starter to deal with, the steering box, steering linkage, automatic cars have the cooler lines, shifter linkage AND transmission kickdown/downshift linkage ALL on the same side. 4 speed guys have the clutch linkage in the way there. Oh yeah...don't forget the torsion bars!

Well guys Anyone who has had the misfortune of growing up Poncho and owning a Goat with A Pontiac motor knows full well what the header selection look like in the performance world you can go with Doug thoreys or Hookers or Headman but I'm going to 99% guarantee you will work for the end result but depending on your Cly heads that can make or break you ..

Dude you fed a whole bunch of people the wrong information.....all you had to do was stick 2 or 3 fender washers on each side on top of the motor mounts which would have raised the engine to gain your clearances that you beat in and grinded off. I've worked on 68-72 Pontiac A bodies all my life.

[@FastMonty]

Thanks for the comment. But, no, that didn't work for me. (Because my engine is already shimmed by almost a 1/4") The point of the video is to expect Long Tube headers not to fit perfectly. There are too many variations between cars for a header manufacturer to make a "one sized fits all" header. Keep in mind, this is for my 69 GTO... I don't know about other years and models. As you can tell from the other comments... others struggled with it too. To your point, yes, there are lots of ways to change engine angle and position. The fun really started when I installed the Tremec TKO, that changed the engine angle dramatically.... so, there's that too. Thanks!

[@sullie35]

@@FastMonty you didn't do something right. As I said before I have worked on the 68-72 A bodies meaning 68-72 lemans and gto. Yeah I know headers are not one size fits all lol... something went wrong for you to have to beat your tubes in and grind on the frame....and no the TKO600 would not have played a role in that either, I have one....but anywho....this was last year

[@spectramitch873]

1969 Lemans with Edelbrock Round Port Heads the 2” dougs headers fit horrible. The drivers side on mine was actually not bad it went right in. The passenger hit the frame and motor mount pretty solid. Lots of banging grinding and cussing. I wish I would have had this video last year. DO NOT BUY THE HEADERS ALREADY CERAMIC COATED. Waste of money you bang it off anyways. Oh and if you already have a custom exhaust already plan on having to modify it because the flanges will not line up at all.

[@FastMonty]

Yep... don't ya love learning the hard way? ha, ha... like me. Thanks for the comment!

[@GTODoctor]

Throw those headers in the garbage and get Ram air manifolds, dyno proven to flow as well as headers. Unless you are building a race car. And you don't have any clearance issues and you won't have to butcher your car like that. Or disassemble for oil change or have leaks... the more you know... 69 Pontiac GTO The Judge.

They sucked went to a doug's headers went right on just had to drop oil filter on pass side..Then I got some edelbrock heads and had to buy round port headers and bought super comps did not fit got into a big argument with summit about it bcuz they wouldn't take them back hence the scratches bcuz it wouldn't fit.. Bought DOUG'S and bolted right up but had to drop oil filter and housing. If u have a fbody 67-9 firebird the headman headers fit pretty good part 1406. Been building Ponchos for a long time.. Trial n error.
