Default 241 Stage 3 RGR Heads

Hey everyone, my buddy has a set of Stage 3 241 RGR heads and he's been trying to find some specs on them. We've searched high and low trying to find something with no luck. Supposedly Rich Groh heads are suppose to be top knotch. His car is currently around 12.2/1 compression. Thinking about changing the heads to PRC 2.5 or 3 243 heads mainly to lower compression and be able to run pump gas... does anyone have an idea which heads flow betters the RGRs or the PRCs??? Any help would be great!! Thank you!

I just purchased the same set of heads. 2.02" Intake Valves, 1.575" Exhaust Valves. Hand ported by Rich Groh.

They're currently at the machine shot for inspection, new spring kit, and a flow test. If you're interested, I'll post my flow numbers when I receive them.
