Hey guy's I am in the process of tearing my car back down this year and while I have it apart I figured I would bump the performance up a little. My question is what would be the best suited head for my engine ? 318 X block 4 bolt mains , 422 cubic inches Eagle rods and Steel crank. Ross pistons. I am leaning toward another matched roller cam when I change things also. The engine has about 11.5 compression with my open Eddy heads now. M1 intake and a 950 HP carb. Bang for the buck which heads would get me the most performance ?

Indy 360-1...But what is your hp or performance goal, and where are you at now? Streeted, or strickly race?

Indy 360s either the 230 0r 245 cnc. I had a set(245) on a 421 sb and made just shy of 700hp with 11.8 to compression.I would think this would really pick up your program.

If you were changing pistons I'd suggest W9's or B1 BA MC's, but since you're doing a freshen, I agree, the Indy's are the way to go.
I would order up a set of T&D rockers right from the start. The stock Indy stuff is garbage.

being u have a 59deg blk,i'd also agree w indy's but for the cubic inch u have the 230's version might work better if in the future u go bigger ci then i would go for the 245's be prepared even used indy's are gonna cost well over 3 g's...but you'll dig the power they make. YA DIG?

Thanks guy's I may be doing a little shopping soon.
