Wonderin what will happen if i put 302 heads on a 351w block...if the compression will be crazy or if its even possible.:confused0006:

not sure about the compression but i know that the head studs are different, i believe the 351's are larger.

Same is same. Check it out.

you can do it, but you'll have to have the head bolt holes drilled out to 1/2" (for the 351W bolts) 302 head bolts are 7/16"

cool thanks.any idea on the compression??
I kind of don't see the point you will loose air flow as the valves are smaller on the 302 heads...
The gains in compression ar minimal at best and of no benifit with the loss of flow...:dontknow:
