I would like to know

Cylinder head wise, the “MAGNUM” style head has only a few, *I Think* 3 choices for the aftermarket. The iron copies, Edelbrock and the Trick Rlow head that does both LA & Magnum blocks. I do not think Indy has a specific Magnum head. They have there copied-ish W2.

MP had several Magnum & cross over styled heads available.
Key word there, “Had.”
I was looking lucky that a fella here wanted to trade a set of Magnum R/T heads which jumped on.
