My dad had a car shop in the old days, from about 1962-1977. We had a machine shop that did just about everything. They were great and if they called up and wanted to do more (and charge more money) my father would ok it. Nothing would get put together until it was boiled, all threads cleaned out, measurements taken etc. First class stuff. We had some parts hanging from wires from the ceiling, like aluminum intakes that had wrong angles on them from the factory. Usually an arc welded bead on them so that they would never be used. We didn't say a word but customers would look at them and see where the magic markers and words etc were.

Took my 4.7 H.O. heads to a shop for new guides,seals and to have high nickel/carbon nitrated stainless valves installed along with having the seat pockets deepened for thicker valve seats..they did OUTSTANDING work..even removed a valve cover bolt that broke perfectly flush that I didn't catch for free !

Hey brother I feel your problems. I also have a engine machine shop in East, Tn and it's 15 different problems every day. And then the customers complain about the price and they wouldn't want us to charge the real amount of time we spend on there parts or they would fall over. Was boring a 454 from .030 to .040 bores didn't have any wear, just a little surface rust from sitting, so I figured it would clean up. Well bored one side and all was good, then about on the 6th cylinder it didn't clean up in the bottom but had .005 left so it would in honing, then went to the 7th cylinder and it didn't clean up at all and now after trying to save the block at .040 for the customer I have to bore the whole block again to .060 but I can't charge the customer double even tho I am spending double time trying to help them get the most from there blocks and should have just cut it out to .060 from the beginning. Grrrrr!!! Or it's like like block cleaning, I've only been charging $50 to hot tank/ spray cabinet a block with a bore and hone job, but yet we chase EVERY bolt hole in the block, wire brush all the rust office, remove all the plugs and wash before and after machining, deburr all the sharp edges clean all the oil gallery holes, rinse every hole and surface on the block with fresh water and oil it down then dry it off and bag it. It needs to be $100 but the shops down the road only charge $50 but the customer don't realize that they don't do all the work chasing the bolt threads and making sure everything is actually clean and no bad threads. People need to realize shops are NOT created equal!! If one shop is higher then your probably getting more done. Just remember, if your not getting charged enough to cover the time to do the job right, then they are not doing it right! People, respect your machine shops! If you want quality work then pay them to do the quality work!! Lol, ok rant over!

[@michaelmartinez1345]

@carsmytruck1 - I strongly agree with You , on the fact that not all shops do the labor the same way... A Good Honest , Knowledgable , Well Equipped Machinist is worth the extra $ to do the work correctly.... One time I took a head and a block to a machine shop to get them hot-tanked... It was a 223 Ford inline 6 from a '61 1/2 ton p/U... When the work was done, everything looked clean, but the head was bead blasted as well... That is when the person who worked at that shop handling our parts said that the head was cracked, and should be replaced or repaired... I noticed that the head was different, than the one that I gave to them... It had closed chambers... The one that I gave to them had the lower compression open chambers. I pointed this out to him and said that all that I wanted done was the hot tank job... He said that the head was the same one that I gave to him, and that he inadvertantaly did the bead blast , so he did not charge me for that work, but discovered the crack after doing the bead blast job... I was very upset-because he had an un-usable head that he wanted to get rid-of and gave that one back to me, and he kept the usable head that I gave to them for a simple hot-tank job... Highway robbery!!! Anyway, one of the most important things about machine shops, is how Honest, (or Dis-Honest) they are... I had to buy another head on Ebay, to replace the head that the thieves at that machine shop took from me. $500 extra after paying for the replacement part & shipping... Good Machining Equipment, Knowledge & Honesty are three elements that are so important in an industry that brings worn / damaged vehicles back to life... Without those 3 elements, the shop should not remain in business... I can supply the name & location of that machine shop to anybody who wants to know which place to AVOID to have work like this done...

[@fostercathead]

The manufacturer should cover shipping both ways to replace the substandard head.

[@BLMCFR]

I fully agree. If they screw up, they should pay for the extra shipping.

[@nrd515]

Years ago, like 40, I bought an intake manifold for my 360 Mopar from one of the big mail order companies. I got it, it had the correct part # on it, and I collected all the other parts I needed to do the upgrades on the engine. Headers, the intake, a 4 barrel carb, valve covers, and a few other items, all came in and appeared to be correct. After I got the OEM manifold off, I start to put the new one on, and something's wrong. NONE of the bolts are even close to the correct angle to go into the heads. I assumed they had sent us the wrong part, so I looked it up in a couple of catalogs and they had sent the correct part, it was just all messed up! I had taken two days off work to do the work on my truck, so this was not good at all. I called the place that sold it to me, and they said they would overnight another one. Nice of them, and I was somewhat less angry about it, but the next moning, I find that the new one was the same as the old one, and it's not going to work. I called them again, and the guy on the phone said, and I had to laugh, "You must be doing something wrong, or you don't have a 318, 340, or 360 engine!". They refused to pay to ship them back, but he assured me that they would refund my money, if there really is a problem, if I got them back to them. We called all over Las Vegas and found a place that had one of the correct manifolds in stock, at a high price. I went over and got it, and it fit perfectly. About a week later, a friend and I drove to the LA area, where the company I bought the two manifolds from was at, and took them in to get a refund. The guy at the counter seemed doubtful there was really any problem, but as soon as I took them out of the boxes, he started laughing, and picked up a phone to call someone down to look at them. Some older guy appeared and he looked confused, and then said, "I'm the guy you talked to last week, and I thought you were crazy, but they totally messed up drilling the holes when they made it!". They gave me a refund on both, and tossed in a hat and some custom window cranks as a bonus for my troubles. I wish I had taken a picture of it, they drilled the holes straight down on them, not at the correct angle at all. The only time I had a major project on a car or truck after that, that went without a hitch, was on car a few years later. All the parts fit, nothing was bad/broken, and there were no "parts runs" to get something we forgot. The worst part was getting the rear end guy's time so he could rebuild and regear my rear end.

Thanks again for a super informative video. Your “rants” are pure education for all of us out here. I’ve bolted on name brand heads out of the box. Fortunately I didn’t have a valve hit a piston due to valve height difference - I did though have a valve job that didn’t seal properly. Due to that experience - nothing I purchase will be “bolted on out of the box” I appreciate you sharing these experiences you deal with daily because there is so many other things to look for/at. Things I hadn’t even considered Keep the classes attention - I’m taking notes 😉👍

[@jacknageleisen3942]

I feel you pain on producing accurate heads to the customer. The out of the box ready to run heads are usually a compromise. Parts are really many times usable to use out of the box,quality control is a tough time consuming task. CNC heads really need a experienced head porter to check them over on every aspect on every part, spring pressure,valve length, seat height, retainer fit,keeper tang position,chamber size, and much more all needs to be addressed. Good video on how important the eye for detail is when doing high end head development. The hand touched by a racing head professional is key. I have made a good living in this business and appreciate you showing what it takes to be the one of the best at this. Great job on theory,prep,honest flow numbers and showing what it takes to prep heads and intake tract that works and lasts. i learn from your videos and I have 45 years in the Air Flow Development game. Its a moving target that still keeps me thinking. Thanks JPS RACING ENGINES

Yeah, Uncle Tonys Garage goes off about crap quality - you should go chime in. BTW, the problem with the Sniper and other TBI based Holley systems running bad on dual planes is because the MAP sensor is on one side of the unit. If there's a full divider on the dual plane, the MAP signal sucks at low rpm. Looks like you fixed that on this manifold!

[@NoferTrunions]

This video reveals what the aftermarket industry is evolving into. Since the people spending the money, customers/clients, are not the ones doing the work, there is lesser need to provide a good product since the builder ends up eating it. They know that the delays and costs (shipping) are such that they can get away with it. So quality suffers. As fewer and fewer people with the money are doing the work, this will continue to get worse. Further bad news is that as far as performance goes, most people can simply buy a new car/truck that has the HP they want. However there are more and more people with money which want something custom, so that helps balance the new car thing. I'd ask for some money back for the blem head. You paid for new and you got 1 blem. If they are willing to replace the head, they are willing to "spend money" to satisfy you. I'd ask for the money or the difference between new vs blem cost.

[@michaelmartinez1345]

Lots of things to look at & correct, to obtain the smoothest/highest and most reliable power from these aftermarket parts... This is WHY I prefer to use the stock cast iron heads on the engines that are being driven daily on the public highways... They perform reasonably well but they have a LOT more reliability than Aluminum heads... Why? Because the critical temperature of aluminum is at 475°F. Compared to well over 1,300°F. for cast iron... One bad overheat caused by a leaking heater hose, stuck thermostat, loose water pump impeller, clogged radiator, etc. Could easily cause any head to heat up to well over 600°F. That could ruin the aluminum head(s) by annealing them and cause them to loose their original strength... That alone should be enough reason to avoid using aluminum engine parts on daily driven vehicles... And on engines with factory equipped aluminum engine parts, if the dealer finds that the engine continued to be operated with low-unpressurised coolant levels, that caused an overheat, that alone could void a factory warranty... I prefer using CAST IRON heads for these reasons ... Cast iron tends to be Much more durable than Aluminum... Worth the extra weight....

[@woodboat3G]

i bought a reman 4.3 gm with a warranty. It started and ran but once you added power it would pop through the throttle body. Same thing you talked about. they wanted me to buy another engine, send that back on my dime and maybe get a refund if they can find out why it doesn't work. I finally gave up and started measuring. The lifters were too tight and NON adjustable. I added the appropriate shims and it was fixed. 20 dollars worth of shims vs pulling the engine and sending it back on my dime.

Eric, I feel ya on the valve job depths varying. Because my VGS20 doesn’t reference off the deck I ended up buying the Goodson valve seat height gage and I use it to find the deepest seat between the two heads and use that seat as the basis for cutting all the others.

[@michaelmartinez1345]

@Gerald Boullester , That is an excellent idea!!! Using an instrument that is specifically made for the measurement of valve face heights, from the head deck heights... Find the depth of the deepest one, then machine all of the others to match this depth. It also helps to match the volumes of the combustion chambers... Awesome!!!

[@65mustang393]

@@michaelmartinez1345 Normally the spindle travel indicator on the VGS20 is close enough but I had a situation where a guy brought two cast iron bowtie heads over and one was a replacement head that was slightly different. Using just the spindle indicator resulted in .015” difference in seat depth. I bought the .375” Goodson seat depth gage, reamed it for the .389” pilots and found the deepest seat and then cut the other seats in that head to match. Then took other head and got a rough idea with the depth with the gage, cut it a little shallow and remeasured with the gage and cut the last few thousandths. I set the spindle indicator to that depth and finished the rest of the seats on the second head. Took longer but everything matched up.

[@bdugle1]

There’s a good reason to trust a true professional to get parts right! Interesting point at the end about Snipers and dual plane manifolds. The Sniper would have to select which injector to use by the firing order if the two sides were completely separated, which is obviously not what happens. It would probably be worse with progressive linkage between the front and back barrels, too. The whole point of the dual plane is to separate the two halves of the engine to avoid dilution, so it sounds like you’d be better off staying with the single plane from the start. Maybe the old torque style low rise from ages ago? Not a power choice, but good hood clearance. Awesome info in this video!

[@coryholbrook4643]

It IS worse with the progressive linkage on a dual plane. I tried that and my car ran ROUGH with a fairly mild cam. When prog mode is selected only the 2front barrels fuel at idle and part throttle so even with a good manifold I had awful fuel distribution. Take the linkage off and deselect it in the software it went back to perfect operation. Seems strange that it would be the case considering a carb works the same way with only a 2 corner idle but the Sniper couldn’t manage it. I did notice when I was running carbs prior to the Sniper install that my 4 corner demon idled a lot better than the 2 corner holleys I had before it.

I understand your frustration the problem today is with parts is it's quantity over quality but they want to charge you the quality parts price.

[@carlosonliones202]

That's a lotta stuff!

The head should have been milled before the chamber softening. Deck height dictates everything else on the head

[@Todd-tq7cs]

Sorry the valve guide dictates everything else

[@thomasbeyer]

Iv seen the dual plane divider exaggerate TBI problems. Put a single plane on and everything was ok then digging deeper one fuel injector was clogged up so with the dual plane it would flood 4 cylinders and the others would be fine. But if anyone has used one of those self tuning efi units the O2 sensor picks up misfires as a lean condition so it then adds fuel causing more misfires and ends up flooding every cylinder until it finally shuts off.

On the first head it also looks like the the left most cylinder has also had welding done around both valve seats .

This ship has sailed, but if anyone else needs more hood clearance with a Sniper the Torker II manifold is even shorter than the Performer. It's not much, probably less than 1/4", but if you need 1/8" it will give it to you. It also has some room to mill the carb pad down a little if needed. I have the same issue with my wife's 73 Camaro and her refusing to do a cowl hood. So far the Sniper has been fine with the Performer she's had for 30 years, but it will likely get a Torker at some point.

you need to point out manufactures so the rest of us can make better decisions. with sales loss they just might get better quality control

[@lourias]

Thank you for sharing your wealth of information. I will double make sure my son pays attention to these things.

[@jbeck6661]

Also won't the valve seat height have some effect on quench and compression?

[@poorfellamycountry]

This is so true, you have my sympathy. Great video!

[@stephencarter1442]

It's your attention to detail that catch this I have zero faith in heads. That's why we have you. It is the most important and often most overlooked part. Joe Homeowner doesn't have dial calipers a depth gauge and we wing it trusting the manufacturer. Sad that everything needs to be qualified before assembly when most people aren't machinists like you and me.

[@magnusdanielsson2749]

I can understand the kind of frustration this would give. Good of you to show some of it and that youre true to the customer.

[@howardcameron1541]

But it is supposed to bolt on , Right?

[@jerrylauber7311]

Absolutely correct.

The redeeming thing here is your gift to all of us illuminating the ignorant to the crap escalating in this industry to make more and more profit at the expense of the professionals and customers. We must bring back manufacturing and jobs to this country NOW. thank you Weingarten, for your patience, time, and insight. The awareness you bring is significant and appreciated.
