West Coast Cylinder Heads is please to announce the completion of our latest Gen3/Gen4 LS7 style cylinder head. The All Pro LSW head opens a new era in cylinder head flow technology with a whopping 400+cfm of intake airflow and 260cfm of exhaust flow. This 12° head is a hardcore cylinder head built to holdup to severe duty in both naturally aspirated and forced induction applications. Extra material surrounds the intake and exhaust ports to insure that plenty of wall thickness is left after CNC machining. These robust castings are available with a 6 bolt head bolt pattern and also have a 3/4" thick deck for a superior head gasket seal. Both LSX and Warhawk bolt patterns are available.
The reinforced rocker bosses include large 7/16" bolt holes and are staggered drilled for rocker stand stability. The LSW heads readily accept 1.625" diameter valve springs and coupled with Jesel or T&D rocker systems provide reliable operation beyond 8000 rpms. They also have factory located intake and exhaust bolt holes to accept all LS7 style manifolds and header combinations.
Currently we offer the LSW heads with a 285cc intake port volume and a 105cc exhaust port volume. Two combustion chamber programs will finish the chambers at 58cc or 70cc depending on application. Milling can adjust the final chamber size to your desired volume. We recommend a nominal bore size of 4.100" be use with the LSW heads. Available valve sizes are 2.200" intake and 1.600" exhaust. Valve choices are stainless steel, titanium and inconel and the costs will vary depending on material and application.
