Highest flowing sbm heads?

Any head with a factory bolt pattern and valves small enough to fit your bore diameter can be used on your stock block. Indy 360, Mopar’s W2, W5, W7, W8 or W9, Edelbrock Victor, or anything else out there I don’t have a clue about. Choose a head and go. Of course, if you do any of these, let us know how it works in the real world.

The engine other’s have mentioned a few times in other threads that Valley Performance built used Edelbrock Victor heads on a Magnum 360 block. They will work.
Yeah you can physically "make it work" but it was a waste of money because you can't reliably make the kind of power the heads can support and the block live.....plain and simple
