LS7 heads are nice, they fit on LS1 blocks nicely, sleeved LS1 blocks of course. To make them work, you will need LS7 valves, rocker arms, lash caps, as well as some sort of LS7 intake manifold or carb setup. Everything else LS1 bolts right up. You will also need longer pushrods, I used 7.750" ones on my setup.
