Speedmaster Chevy LS1 LS6 Bl101Xx Cylinder Head Core
746-PCE281.1082
These Speedmaster MLS head gaskets feature 100% stainless steel construction. We don't use inferior mild steel like some other aftermarket gasket suppliers. To aid in sealing, both outer layers of our MLS gaskets are covered with a high-temperature coating. You won't find a better value in head gaskets for an LS anywhere.
INTAKE / EXHAUST GASKETS
Unlike most other Chevy V-8's, the LS-series engines utilize individual O-rings around each port to seal the intake manifold to the cylinder head. The LS1 / LS2 / LS6 style heads & manifolds use GM pn# 12533587 and the LS3 / L76 / L92 style heads use GM pn# 1290125. On the Exhaust side of the head, all non-LS7 heads utilize the same MLS header gasket. The part number of the exhaust gasket is GM pn# 12901125.
Speedmaster is currently working on a line of MLS exhaust/header gaskets. Check with your salesman to see if we have an MLS exhaust gasket available for your application.
