Ok so I'm build a 318 stock bore flat top pistons new bottom end either a 454 lift cam or a 480 lift summit grind 4 speed is putting 360 J heads on it going to help it or hurt it

If you want a 318 hit the easy button and get a 5.2 magnum. Better compression and heads, as well as a roller cam on the cheap.
