Flowtek head follow up

Sharing flow numbers of modified vs. non-modified flowtek heads.

[@HammerHeadGarage]

I got 23cfm on the exhausts and 17cfm on the intakes. I noticed a big diff in power over the P heads tho especially in the higher rpm range. The Floteks are not garbage. They work.

[@Diondo26]

damm good numbers ....I ported mine too and they work just perfect ..with 331cu F cam and 1.6 Rockers ..i,m impressed how good they flow.....

[@79beans347]

Man you are pulling some awesome numbers out of those heads especially with 1.94 valves because from what I've heard 300 is about all u can expect out of 2.02 valves and your just about there and that's some awesome skills that you have

[@allenjay5907]

Nice , I like the fact you made a tool to map the port .

[@FXRSDriver]

Was it you asking me about an intake awhile back?

[@allenjay5907]

FXRSDriver yes sir , I hit up T miss and his reply made me have a bunch of respect for you sir . I value that more than most . What Toms brother emailed me was the intake isn’t the bottleneck . It’s the P head , I’m not wanting to put much money in that head , I don’t like the pedestal rocker set up , and I’d be better off saving my money for a set of decent heads and a better cam . B cam and 1.6-1.7 rockers works fine for what this head is capable of . I put a set of gears in car and drag radials I’ve had a ton of smiles per gallon. I sold the drag radials and I’m going with Hoosier quick time pros on my16” cop/taxi steelies . Working out some bugs now and driving the car . Y’all rock down there love the content .

I got a set of those sooner. You're the first guy to give a positive review! I wanted to use them on my pump gas 351w just to avoid detonation. Also thought bout buying the crank and building a 393w? Got everything but the crsnk?! Your finish numbers are hitting on Victor Jr numbers!

[@FXRSDriver]

You can get the whole set up through fordstrokers, go for the cubes.

[@markmccarty9793]

@@FXRSDriver I just need the crank. Now, of the kit comes already balanced! Or, just put a 357w together and shoot the 100 shot on it from time to time! I know, could use it on the 393w! Save you the time of typing. This is a personal challenge for me to build a junkyard dog for as little as possible! With junk literally lying round! If I had a t5 I'd put it in the old Fairmont wagon, it has no ac, ps, pb and was already a stick car. Put a 460 in the truck!

[@fox5.043]

Nice work, ready to see them in action.

[@angry408w7]

i had ootb flo tek heads in a stock 302 with a b cam trick flow intake and longtube make 300 to the wheels no tune. awesome heads for the money.

[@terrygrover6440]

I think you did a really good job on this video

[@frontdizzy2218]

Great info & even better port work

[@jackrabbit7389]

These heads as tested on Rays bench untouched rival AFR 165 renegades and TFS 170s

[@andymartin4747]

I was looking at a set of heads like these bare. I feel a little better about them and what they can do after I hog them out some. Great video!

[@FXRSDriver]

I stay away from the hogging out term...LOL!!! If you buy them bare go with the 2.02 valve ones, and use good springs and hardware. I wouldn't even trust the rocker arm studs that come on those.

[@andymartin4747]

FXRSDriver thanks. I’m ordering everything I need to check the spring rate and install height. I was going to use everything off my 70 351w heads.

[@FXRSDriver]

@@andymartin4747 stock up on spark plugs for those heads, they'll eventually be scarce.

[@Joel50PR]

Regarding the flow numbers from Flowtek, looks like the rows are switched. Meaning that the 0.200" flow numbers are the 0.100" lift figures, the 0.300" are the 0.200", etc. That is if you compare them to the ones that you measured.

[@FXRSDriver]

Most likely the case.

[@arturo5819]

Ltd going to the 6s for sure

[@FXRSDriver]

I told Rod that when he first got into the 7.0X range that putting these heads on will get it into the 6s for sure, now it's a matter of seeing how far into the 6s it'll go. There's a couple other things I'd like to see him try before the head swap though.

[@thenewBH]

David - have you ever thought about building a simple manometer/shop vac 'flow bench' for your own benefit? I have one I built for under 100 bucks and it's incredibly useful.

[@FXRSDriver]

No, saw something about one in one of vizards books, and thought of building a bench too, but really don't have anywhere to put it. if i had one I'd never get anything else done...LOL!!

[@thenewBH]

@@FXRSDriver yep, that's what I built. Works good and it's really just a board hanging on the wall.

[@black88coupe]

VERY COOL!

[@reloadingfun]

i bought one of those heads, they had a lot of core shift also. did yours have a straight drop off to the seat on the short turn too?

[@foureyedstang6035]

I just got a set of FloTek 185's bare. I wanted to add bigger springs for a TFS stage 2 cam, .563 lift. What length valves do I need to get? I want to go with a Ferrea valve. I want to do them just like you did by cutting down around the seal area to fit a better spring. Any info would help me out. Thanks

[@juicedcoupe]

David, I left a message for Rodney but haven't heard back. Did you guys fair okay?

[@FXRSDriver]

Yeah, Kevin lost some trees, and fence. Pirate got the worst of it with standing water in his garage.

[@juicedcoupe]

@@FXRSDriver it's good to hear that you guys came through okay. Some of the pictures from over that way looked pretty bad. We were ready for it to hit here, then it shifted.

[@FXRSDriver]

@@juicedcoupe Yeah, I think a lot of people were caught off guard when it hooked right then slowed down. Dropped a lot of rain, ground was saturated, so when the winds came it blew down a lot of trees.

[@juicedcoupe]

@@FXRSDriver We were in a similar situation when hurricane Georges hit in 98. Some smaller tropical systems had dumped a lot of rain on us in the weeks before. When the hurricane hit, huge trees were blown over, ripping the whole root bed out.

[@torapruitt9491]

I got a 302 I want to get some trick flow heads an a lunati cam with. 535 .544 lift with .224 .232 0.50 duration I want to run 1.7 rockers and maybe some nitrous ,do u think they'll hit

[@FXRSDriver]

There's no way to know, you've got to check. Due to the valve angles most likely not, but you've got to ensure yourself when you put it together.

[@torapruitt9491]

@@FXRSDriver so its really safer to go with 1.6 rockers

[@FXRSDriver]

@@torapruitt9491 It's not the lift, it's the duration. Pistons are at or near the bottom when the valve is at max lift. Always a good practice to verify clearance during assembly.

[@torapruitt9491]

@@FXRSDriver do I need to put clay in between head an piston or something else?

[@FXRSDriver]

@@torapruitt9491 Yeah, can just get playdoh and put some in and around the valve reliefs then measure how thick it is where the valves contact the clay. You'll want at least .100 on the exhaust and .080 on the intakes.

[@jdrods1519]

Awesome! The LTD will be flowing freely! 💪🏻🇺🇸

[@fitbike395]

Would you recommend flotec?

[@FXRSDriver]

If you can do some minor work to them they can work well. I would buy them bare, then add good hardware.

[@andymartin4747]

What length are the valves for it? I just got a bare set.

[@demyshernandez240]

What was your pushrod length

[@FXRSDriver]

With these heads? Don't think he's put them on yet.
