1. from wat i understand the 351W's intake is 2" wider than the 302 intake, correct or no?

2.will 302 heads work on a 351W, and will they raise the compression of the engine, and can i gain any type of hp/tq, on the bottom, mid and high end's?

ive heard alot of ppl say that u can pull hp/tq from 351 heads on a 302, is it the other way around too?
