360 Magnum Build w/ V Belt Configuration Question

Six Barrel Bill said

We tore it down because we had no idea the condition of the engine. It freaking looks brand new inside. We are going to change heads, cam, intake and possibly bump compression any way.

This is what I wondered. Before selecting an intake, figure out which heads you are going to run. The only decent Magnum head right now is the Edelbrock Magnum head. But if you definitely want to change heads and intake, and definitely want to use v-belt LA front accessories, you could convert to LA heads and rocker gear, and an LA air gap manifold at the same time.
Not trying to steer your build, but you may have more parts to choose from if you go that way.
