got a set of 601 heads layin around that are in good shape been thinking about putting them on my 305 tbi truck and cam like maybe a comp xfi 12-366-4 cam and maybe doin some porting and of coarse fuel upgrades. what kind of power would yall think i could get out of this? I was wanting 300hp 350 but this would be much cheaper and easier. what is the max lift on the heads? Any opinions on cam choice and porting? remember this is a 4x4 truck so nothing to wild
