They often do that, RSR rebuild is scheduled for every ~20hrs.

I had the lower fins on my my heads welded up to prevent that sort of thing

1. What other parts (e.g. valves, head studs, rod bearings) typically need to be replaced at the 20 hour rebuild?

2. What is the rated max RPM?

Any and all of the above, they are strippped and completely inspected.

A 993 RSR sprint motor is 340hp@7000, 380NM@5500

there is a lot of variation depending on the series

Bill. Picture is of 964 RSR head. I assume they are drilled for either 964 or 993 flange configuration. Would that be correct? Thanks!

I've only seen 993 heads like that but it's quite possible that they started doing that w/ 964 3.8s too.

I know that they first used the 993 exhaust setup on the 964 3.8RS
