Default Flow sheet for GTP stage 2 243s?

Does anybody have any flow sheets from a set of GTP stage 2 or 2+ LS6 243 castings from around 2003 or so. I came across a set for a good price with only 300 miles on them, they already have a good dual spring &titanium retainer setup on them also.

How would these compare to maybe the TSP or Livernoise LS6 stage 1 offerings. They both claim 305-310cfm with factory 2.00" & 1.55" valves.

Was hoping some of the older crowd might have some info, or valued opinion about these heads.
Thanks
Floyd

Stage 1 Prc heads look like this. I put down 460//414 to the wheels with these heads and an ms3 cam from TSP. I'm still missing a few bolt ons also.
