GMPP LS1 GT-2 Heads
Hmmmm... these look alot like the C5R heads.... Anyone ever heard about these? It doesn't give alot of specs about them besides that they are 38cc and 11* valve angle, which means around 15:1 on a stock internal LS1

It's going to race the Ferrari's and 911's in ALMS.
I'm suprised it was allowed in actually. It's actually the RENAMED version of the C5R Heads, there was a 0005 first design part number and this is the 0090 2nd design part number. GM and Katech realized that the small chamber and small port were needed in the restricted 7.0L race motors.
