Patriot Performance LS6 Style Heads
I've decided on Patriot Performance Stage II LS6 style heads, but I have a question...What is the differance between the four different stage II heads? I've used the search, but I couldn't find an answer...Thanks, Ryan

Notice: 59cc and 64cc chambers....(different chambers)
Notice: 2.02/1.57 vs 2.055/1.57 intake/exchaust valves.... You'll probably gonna be fine with 2.02/1.57 valves.....depending what kind of power you're gonna make....For ~420rwhp it will be fine....

Smaller CC will net you more CR and more power. Depending on your cam you might want bigger valves.
But in choosing a head look at the midlift flow #'s .200, .250, .300, .400
High flow in those areas is where the power is at.

You would have to find out about your PTV (piston to valve) clearance to decide.
TSp 233 or T-rex will work with stock heads without fly cutting the pistons for clearance.
I think the 231/237 should clear with 2.055"/1.57"/64cc but you better call TSP to find out for sure.

I wouldn't necessarily jump head-first into a valve 'upgrade'...Call the valve manufacturers, and Patriot, and ask for the grade of their standard stainless LS1 valves. The valves I know of that are supplied with the 'upgraded' option, I believe, are a lesser quality stainless than Patriot's valves. If I recall correctly, other than their's, they only offer Rev valves (the 'upgrade'). But don't quote me on that one. You'd have to call Gunnar.
Chris, PP does weld their chambers before the CNC process to get their chamber sizes. They are supplied at factory deck height unless otherwise requested.
