quick 318?

Are the "302 casting" heads that bad?

I run 14.8's with my stock 318. I have the "302 casting" heads :sad10:

I'm looking to do upgrades this summer when I have time.

How good do you wanna get at porting? 302 heads have the benefit of a closed chamber (read more compression and a quench pad) Unfortunately they have small ports and something like a 1.78/1.50 valve so that can be a restriction
