Performance with those heads will be down a good bit compared to an LT1 head. The runners on the L99 heads are a little smaller than the LT1 heads and the intake valve is only 1.84" compared to 1.94".

GIZMO, what is the chamber size? I would guess compression would be a bit out of hand on a 350.

Im guessing you mean the 4.3 heads? Have you checked to make sure they are the 4.3 heads and not the cast iron 350 heads?
