BTW anyone who wants these heads for their 302-331 let me know....if not to E-Bay they go!!!

Thanks, ive gotta see what he recommends for a head. I do have Shaft Rockers and a pretty massive intake....so 225 might not hurt. But i did want to keep the RPMs below 7000. Whats awesome is that hes in state. So i can go pick it up myself.

Yeah seeing the price difference is only $200 and i plan on a supercharger/ turbo in the future

how much do you want for the heads

Click to expand...

$750 Shipped They have 1/2" holes so you'll need dowels if its going on a 302. I had them O-Ringed so they'll be good if you're running nitrous, S/C Etc.

These heads have 210cc Runners but the actual flow numbers are comparable to a AFR 165cc. It includes Valves/ Springs/Retainers/Bronze guides. No studs or guide plates. Springs are good up to .600 lift. If you live close enough and don't know how to install heads ill install them. (For the right price of course)

Ed is the mad scientist in the hills. Good thing we have e-mail. LOL....if theres a problem i will personally drive to his shop and leave an email on a brick. J/k

A N/A SBF combo isn't hard to figure out. I gave him plenty of info.

As for the heads They're on my engine right now. They're in excellent condition seeing as i put them on about a year ago and the car doesn't get driven much. I'll either toss them on E-bay or toss them on the short block 302 in my garage. and start building a second motor.

UPDATE from Ed Curtis

Afternoon Christopher,

I did run through quite a few calculations using the AFR 205 heads and the AFR 225 heads as well as various camshaft profiles and we would be looking a project with close to 525 HP with the 205 heads. As long as the headers are a match up to the exhaust ports of the AFR 205 heads. About 25-30 more with a big set of tubes made for the larger 225 exhaust ports. Quite a stout powerplant.

Let me know when you're ready and we can get this done.

Ed


So whatcha guys think?? AFR 225???

Thats more power than i planned.... If i made around 550hp with this N/A setup i would be excited!!!!

Yeah but you have a bigger motor. So i suppose it will take bigger heads and a more radical cam to make the same numbers on my smaller engine.
