Cometic C5403-045: Head Gasket, MLS, 4.200 in. Bore, .045 in. Compressed Thickness, Chevy, Each - Cometic MLS head gaskets are constructed from multiple layers of stainless steel for strength and contain load-controlled embossments that conform load distribution across the sealing area. This creates an exceptional seal by requiring less clamp load resulting in less bore distortion. The stainless steel outer layers utilize FKM (Viton ) rubber coating, a high-temperature and chemical-resistant polymer. A topcoat of PTFE aids in resistance to fret and increased cold sealing. MLS head gaskets are available for most aftermarket cylinder heads; as with all of Cometic's MLS head gaskets, no sealants or re-torque is required. Cometic. C5403-045 fits these applications: CHEVROLET 6.6L/400 Chevy small block Gen I, CHEVROLET 5.7L/350 Chevy small block Gen I, CHEVROLET 5.4L/327 Chevy small block Gen I, CHEVROLET 5.3L/327 Chevy small block Gen I, CHEVROLET 4.9L/302 Chevy small block Gen I.
