Manifold fitment question

As others have already stated; maybe, maybe not, though if it were me, I would do the compensation cut on the intake, if the chamber side was cut .040.

If you were to angle mill the heads.....alot of work, but you can get a real tight chamber and compression boost.....I would say you must check piston to valve clearance, and most likely you will be having new eye brows cut into the crown for clearance.
