Victor Jr. LS
These Pro-Port cylinder heads are cast for custom ports and combustion chambers and are intended for head porters. Cylinder head 350-77379 has been machined for the LSX 6-bolt GM block while head 350-77369 is machined for the stock GM block.
All machining, with the exception of the exhaust flange and spring pockets, matches the stock GM LS7 cylinder head. This also includes valve location and angle, spark plugs, intake flange and accessory bolt holes on the ends of the head. The cast ports and chamber are undersized for the custom porting possibilities.
The port design allows for both the valve seats and guides to be in place for custom porting applications. Both heads also include black oxidized aluminum rocker stands.
