I'm looking for some new heads for my 89 gt and saw these just wondering what u guys thought about them.. Car has stock bottom end as far as I know and has stock e7 heads number 2 spark plug has oil on it I'm sure that the valve steam seals are leaking and I'm sure the lower intake probely has seen it's better days. I'm in a toss up between the trickflow 170 r or the new 11 r I don't really want to spend the extra cash on the 11r but I think it might be best for when I build my 408 I'll just toss those heads on it what you guys think. Or would the 170 r be ok on a 408 eventually. Thanks ..Dan ..

There may be someone with evidence saying otherwise, but I think 170cc heads would be choking a 400ci engine. Perfect for a n/a 302. Terrible for a 408.

Those are probably Pro Comps which are a Chinese knock off head.

From having been there and done that, there are 2, maybe 3 companies to use besides OEM for a 302. Trick Flow, AFR and maybe Edelbrock if you get a good deal. My personal preference is the Twisted Wedge head. The TW head will make plenty of power on a 302 and has a lot of "meat" for porters to use if one decides to go bigger. Fox Lake routinely ports TW heads out for use on 408s although they will choke a 408 without said portwork as will any 302 head.

Although... I would never build a small block these days. You'll pay more for a built 408 than you would for an Aluminator Coyote and the Coyote is in a completely different universe.

And if one is stuck on a budget with the 302 for awhile, just supercharge. You'll make 100rwhp more at least than a HCI and retain the stock street manners and gas mileage while out of boost. Pushrod 5.0s LOOOVE Vortech S trim superchargers.

If you are gonna build a 302 then build a 302 and do it right as most of those parts will not be a good match for a 351 stroker

If you are gonna build a 302, build a DART based 363 stroker the first time and be done with it. And spend way more than you would for the Aluminator...

well basically what im looking for is buying a set of heads once. either the twisted wedge 170 R head or the new trick flow 11R 190 CC head. what I would like to know is in the future when I do decide to build a 351 windsor will these heads work on it im leaning more towards the 190 cc 11R heads. I am currently sticking with my 302 at the moment untill I move back to the US once there ill do an engine build but untill then i need some new heads and only wanna buy once.

But you don't just buy heads once, that isn't how it works. 190cc will be HUGE for a 302 and they likely won't even clear the stock valves with any decent cam. You will also make all your power up top with a completely anemic bottom end. If you are completely dead set on only buying once then get the TW 170cc heads like I said. Later on when you are ready you can send them out to be ported to a 205cc or whatever.

im just looking at options guys. like I say ive been looking at the 11r and like them u think they will be to much for my 302 there is some cam in there not sure I think its an alphabet cam not sure since I bought the car used from another soldier. whats on the car now stock bottom end with un known cam. holley systemax 2 upper and lower cai, pp throttle body , bbk long tubes x pipe, and msd 6al 2. car is a stick. my stock heads are **** and the seals are leaking they need to come off. im am not putting them back on so new heads are in order. after I get back to my duty station in Germany after this afghan deployment im putting heads on the car and want to get some decent heads. I will be stationed there about another 6 months before I move back to the usa after that then I can build my stroker im thinking a 408, which is why I was wondering if the 190's will work with a 408 I will sacrifie loosing a little bit now on the 302 with bigger head until I build the stroker in about a year I will recam the 302 as needed for the bigger heads what do you guys think??? thanks Dan.

Any head you can currently run on the 302 is going to choke the 408. The only half decent option is an AFR 185 head. You'll have 0 low end but it'll pull up top with the 302. The 408 will have a lot of low end but fall flat on its face up top. You also will have an extremely limited cam selection with 185s on a stock 302.

Like I said, I would get the TW 170s now, enjoy them while you build the 408 bottom end and then send them out to get ported to 205+ for the 408.

61cc for the stock motor. You can always have them milled later or just run a higher/lower compression piston when you do your build. I linked to LRS. Summit is good too. You can also get a military discount on Jegs, you just have to verify with a rep that you are military. Email them and they'll set you up with an account.

edit: Damn, Jegs doesn't carry them wtf... well its still good to know you can get a military discount on Jegs. You can on AM too but... AM also does not carry them...

Bro if you are gonna build a 408 in 6 months or even a year save your money for a dart blocked 427. Do not waste your time building a 302 and hope that those parts will be optimum for making power.


Like we have said earlier if you wanna build a small motor use the appropriate parts and if you wanna build a larger stroker motor use the appropriate parts. Slapping a 351 stroker together will run up the bill faster than you think. Get ready to upgrade the tranny, rear end, suspension/chassis and brakes.

This x100000

If you don't have $15k-$20k to do the build, don't even bother. Engine done right is $8-$9k, $4k for a Magnum or built auto setup, suspension/chassis another $3-$6k depending on what you do and then there is the rear, any bolt ons, safety stuff etc...

Cheaper to buy a clean 2011 Coyote than build a pushrod or a modular and the returns are much higher. One reason I'm probably selling my Teksid block and all the other modular build stuffs I have in my garage. IMHO, noone in their right mind would not do a Coyote swap but that's just me.

Like people have stated already, it will be cheaper in the long run to just build it once. If you want to use the block you already have, then buy the TF Twisted Wedge 170's and install them right now. And just use whatever cam you got in there for the time being.

When it comes time to assemble your bottom end, with whatever cubic inch stroker kit you choose, send the heads off to get opened up. And have a custom grind cam made to tie everything together.

I know that it sucks when you ask for help with something and everyone says to buy something else, but in this case they are trying to save you time/money/heartache. Building a 302, then turning it into a 408, is going to cost a lot and probably still not have the results of some of the options mentioned. The parts that will be mediocre on a 408 are still way too much for the 302, and parts that are baller-status for the 302 still aren't enough for the 408.

Your best bet is probably a set of gt40 heads and a Vortech supercharger.

I mentioned to him already that he could just pull his E7s and get them refreshed for dirt cheap and then slap on a Vortech. Viola, instant 400hp. And if he does go ahead with a 351 build later on he can just upgrade it to a T trim or YSI.
