With the valve relief I dont know why it wouldnt,also in other cases depending on milling and or gasket thickness..

Is this for a 346? Those heads are better for larger cubic inches. The LS6 2.5 should. but the runner volume is still kinda big. The stg 1.5 would be better andmost will recomend the 5.3 heads because of runner size. If your looking at the stg 3s, why not at thier new 215 head?

Im running the 2.5 LS6 heads with an MS3 on a 113. But with a -4cc piston.

I already have the heads on the engine...Was there when I bought the car. It should be good for high RPM I think!
