Hello, Im wondering if newer gt40p heads will bolt up correctly to my 68 302 block? Has anyone ran this set up before? If they do in fact fit, will I need to update the intake to efi as well? Im looking at these bad boys right here.

thanks for the pointers.

Yes they will fit, no you will not have to convert to EFI, you will have to select headers carefully. "P" heads have a funky spark plug angle. I think it's very curious that they spec a 1.94" intake valve (stock is 1.84") and make no mention of porting...

Here's my $.02:
- Those are quite expensive for what they are. Plus, you will have shipping and they are heavy (+$$).
- The stock valve springs are pretty pathetic, even when they are new. If you have any kind of an aftermarket camshaft planned or even roller rockers you really should upgrade the valve springs. Another $150 on the tab...

I'd leave them, sorry to rain on your parade.

I agree with Pete not sure with that and it also states on the bottom that they weight is 26 lbs. I would call them and see what's up with the points stated above also.

it also states on the bottom that the weight is 26 lbs.

Wow, I completely missed that, thanks. There is no way an iron head weighs 26#. That is about what an aluminum head weighs.

ok awesome, thanks for the tips. What about these right here?

Ford 5.0 High Swirl - $649.99 : Tri-State Cylinder Head, Remanufactured Cylinder Heads

are they worth the extra hundred bucks?

More over priced and over rated junk, imho. I'm extremely suspicious of head that isn't accompanied with a flow chart. Plus, 64cc is getting big for a N/A 302.

What are these heads going on? How much power do you want to make?

 

[kingleodiorio]

Im building a motor for my 67 coupe. They're going onto a 68 302 block, fitted with hydraulic roller cam, lifters, and roller tipped rockers. My horse power goals are relatively modest, im looking for maybe 320-350, daily driver style, naturally aspired. Of course money is a big factor in all this, I just wanna get the best bang for the buck. I'll be honest, I dont know very much about selecting the right parts for this project, or any project for any matter, so all suggestions are welcome and will be considered.

If you cannot afford TFS 170 heads then get the edelbrock e streets. Be sure to get the right springs for the cam you are going to use. And call Comp cams they will help on their end.

So those are E6 castings ported and with bigger valves.......see if they can supply a flow chart as that would be interesting.

ok ill contact those folks and see what they have to offer. There are also another pair of flo tek aluminum heads for about 800.00$ Ford 5.0X Studs & Guide Plates Flo-Tek - $798.00 : Tri-State Cylinder Head, Remanufactured Cylinder Heads
I may just go with these, they've been proven up to a 50 hp gain according to Fox Mustang Cylinder Heads - Budget 5.0 H/C/I Swap - 5.0 Mustang & Super Fords Magazine they seem like real nice heads. right?
