For the guys that's wondering how these heads will do with the MS3, I'm getting the car tuned right now at Vette Docs in NY.
My setup is PRC LS6 stg1 heads, MS3, Kooks 1 3/4 w/offroad pipes., ASP pulley, Halltech stinger, ported ls6 oil pump, FAST 36lb inj. and stock TI exhaust. The car is a 03 Z06.
Baseline without tune was 430rwhp. After a little tweak, it put down 461/409. There's still more tuning to do, but so far it's looking prety good. I will post up final numbers and graph when it's all done.

Thanks Jason, I spoke to you a couple of times over the phone regarding my combo. I will def. post up the sheets tonight after it's all done. Also want to take this chance to thank all you gents at TSP for your help on my project, everything went very smooth. And a special thanks to Jon for making sure the injectors showed up for the tune, as well as his help on rest of the parts.

Final numbers. First run is untuned and the final run.
Special thanks to Carmen at Vette Doctors for working his magic on tuning this badboy. Before the tune, the car was barely idling but now it's very smooth. It still bucks under 1500rpm, but that's just the nature of a cam like this size.

Does anybody know what might have caused that little spike towards the end right before the redline? It looks like it was dropping off and jumped up all of the sudden.

Just the way the dyno ended the run I guess I need to get back out there & keep building these heads.

I'll let Jason chime in on the PTV clearance as I couldn't measure them.
I ran the heads out of the box with STOCK size LS2 valves, which is why these numbers are really impressive. Not milled, no additional porting, nothing. Jason installed the PRC dual gold springs on them and I just took the heads out of the box and threw them on the car. No flycutting, that was one of the main reason why I went with the heads.
