Clearly the industry’s most efficient replacement for LS1, LS2, and LS6 cylinder heads, BMP's LS Aluminum casting delivers more power than other aftermarket heads in its category. A number of important features set the BMP LS 15° apart from others, including having the same 15° valve centerline and rocker arm attachment angles to ensure correct valve train geometry when longer valves are employed. The highly efficient 235cc intake (2.080” Valve) and 87cc exhaust ports (1.600 Valve) provide outstanding flow. You have a choice of 64cc or 72cc combustion chambers.
Want even more flow and power? BMP offers Aluminum LS 15° heads that are CNC-ported. The intakes have been enlarged to 255cc runners while the exhaust side has also been enhanced. The 2.080" intake valves are still employed. Available as bare castings or in race-ready assemblies that have a multi-angle valve job and radiused exhaust, are equipped with Manley stainless steel valves, high performance springs and Manley chrome moly retainers. Compatible with stock LS1 rocker arms and OEM stands.
They’re available bare, or in two different assemblies that are designed to match your camshaft’s valve spring requirements. A multi-angle valve job and Manley stainless steel valves make the assemblies an excellent value and a real time-saver for engine builders.
