SBF Heads
I'm looking to build an engine, I looking at three different sets of heads. The first set is 1963 289 rebuilt with dual spring capable of 550 lift. The second choice is a GT40 type and also GT40P the 40 is aluminum and the 40P are cast iron both with springs up to 520 lift. I have also seen deals on aftermarket aluminum heads complete for about $620. The engine I'm looking at is a 302 bored 30 over with flat top pistons. I'm looking for the best heads to have some fun with.
How much do you want to spend? Afr makes a good small block head.Stay away from pro comp,they are cheap,but you get what you pay for.

For the right money, I'd go with the GT40 aluminum heads and a full roller block. Can be done relatively cheap if you shop around.
Thanks, I have wondered about the Pro Comp heads as well as the GT40's ... Roller sounds cool but, I don't know if I want to go that way..
If you have the choice go with a roller cam. Reducing friction is free power, not to mention much better cam profiles.

Low buck, touring style, '73 Convertible "rolling restoration", 351c, 2v heads with a shave and a haircut, Performer intake, Holley 650(ish), roller rockers, screw in studs, guideplates, stainless valves, Duraspark / Motorsports MSD, T-5 conversion. 1-1/8" front, 3/4" rear swaybars KYB shocks and some home brewed subframe connectors. Future plans; JGC steering box, Cobra brakes and... paint, interior, etc.

When I die I want to die like grandpa, peacefully in my sleep... not screaming, like his passenger.

Given those 3 to choose from I'd pick the aluminum GT-40s. I've used them before with good results on very modest builds. Make sure they are ready to run. If not dial in the extra cost of a valve job and perhaps guides. The AFRs suggested by73mach1 are excellent heads, best out of the box I've seen, but are not cheap. Chuck
