88958758 CNC LS3 Cylinder Head Assembly Features:

The CNC-ported LS3 head features 276cc intake runners and 92cc exhaust ports, along with a combustion chamber volume of about 68.5cc. That's the same volume as stock LS3 heads, which maintains the stock compression ratio. It will fit any LS engine with cylinder bores of 4.000 inches or larger, including 6.2L L92 truck engines.

Each head is delivered fully assembled, with 2.165-inch hollow-stem intake valves and 1.59-inch solid-stem exhaust valves, as well as valve springs, valve locks, spring retainers and valve stem seals. The maximum recommended valve lift with the stock valvetrain components is 0.550-inch.
