All,

I'm looking for photos of CNC ported small block Edelbrock RPM heads.

Any issues with breaking through exhaust and valve cover bolt holes? should they be epoxied?

Thanks in advanced

what about the breaking through on the bolt holes? should I epoxy them?

I would, plus sealing the threads on the bolts that broke through. The heads in the pics are SB magnums. I had the intake manifold bolt holes redrilled to accept an LA intake manifold that I want to use. When Hughes redrilled and tapped them, they broke through to the water jacket on 3 of the 4 end manifold bolts. I obviously had leaks on fire up when the coolant pressure came up. I was able to reach in to the water jackets and seal those 3 corner break throughs from the back side with JB weld. Leaks fixed.
