i was thinking of going to some 1.6 ratio roller rockers sometime soon, what do you think about this? is it worth the money? im planning on swapping in some used vortecs and the sdpc tpi intake im shooting for 310-320 hp with these mods and my previous ones in my sig. is this reasonable?

 

wouldn't hurt but i believe the gain you see will be small. i'd buy steel and not aluminum for the street. i like comps 1318s
