well heads ended up being ok. i picked up a 2012 ls3 shortblock from slp with 3 miles on it...the reason my ls2 popped a piston was the factory fuel pump wiring....i picked up the racetronix hot wire kit for the fuel pump...my fuel pressure was dropping in the upper rpms off even with the new pump. cars back together and put down 526 rwhp... very happy with the car....now i want a c6 vette or a c5 z06 lol
