Pits, they are the edelbrock race heads.

Looking at the specs from the Summit page, it looks like the intake valve is mover .150 as it talks about having to use big block rocker arms:

Notes: These heads are designed to accommodate stock big block Mopar rocker arms or similar aftermarket brands with a minimum of 0.150 in. intake offset. Ductile iron adjustable arms can be used but will require special clearancing of the rocker arm body in order to clear the valve spring retainers. Arms that are not built to stock specifications may require special modifications.

I want to get a set of aluminum heads, but don't want the regular edelbrocks. The Trick flows are taking forever to release. I am trying to get a set of Promax from Marsh Performance, but he cannot get the heads in stock.
