Default TSP's PRC stage 2.5 CNC ported ls6 heads?

I see these on their website, but they don't have any flow numbers, dyno charts, or even any claims on power. Does anyone run these? Everyone I see on here seems to be running their stage 1's. How much of an improvement are the 2.5s over the 1s? Is it worth it, or go another $400 for the terminators? Thanks in advance!

I just bought a set of 2.5 heads. They don't have flow #'s yet for these with the upgraded valves. The flow #'s for their stage 1 are on their website. I will post my flow sheet when I get the heads.

I just used a set with a 228r. Great power all the way through the rpm range.

Old motor stock shortblock with Patriot stage 2 (6.0's ) and MTI C2. New motor Sytage 2.5 TSP's, MS4, and forged shortblock. Waiting for track time right now. Dyno #'s were 26+ for new motor with 2 miles on it.
