I know it has nothing to do with valve cover mounting. But what I getting at is when you start researching heads on the market and find one that doesn't have center bolt valve cover mounts, more than likely, not always but more than likely, they are targeting the standard 350 engine, not the TPI L98. I guess what I'm saying is if you want to use your stock intake manifold on your L98, make sure its bolt pattern lines up as well.

There are lots of head variations that can, and should be considered, but none are dependent on whether the head is perimeter or center bolt valve cover mounting. Hence post #2, which states, "There can be lots of differences in heads. However, the valve cover mounting only affects how the valve covers attach, nothing else."
