Nice 
It's hard to beat GM's LS3 cylinder heads, so we didn't even try. Well, that's not entirely true, so for this build we went with their Chevrolet Performance CNC-massaged heads (PN 88958758). They arrived complete with 2.165-inch hollow-stem intake valves and 68.5cc combustion chambers. At 0.63-inch of lift, they flow over 359 on the intake side.
