I want to upgrade from a 302 to a 351. The 302 is carburated with a 650 holley DP, x-303 cam, gt-40x heads, edelbrock performer rpm intake, 1.6"lifters. I want to know if these are compatible with your average 351w block. I know the intake manifold is, but i wasnt sure about the heads. Anyone know what can and cannot be swapped onto the 351? And also what upgrades might you reccomend. Thank you.
