About This Product
This Cometic head and base gasket kit is the professional choice for servicing a 4.500" big bore Milwaukee-Eight engine. The kit includes .040" Multi-Layer Steel head gaskets and .020" Rubber Coated Steel base gaskets, providing a reliable seal for high-displacement custom builds. Designed specifically for 2017 to 2025 M8 models with 4.500" bores, this kit requires the cylinder heads to be plugged or welded, as the gaskets are only embossed for the bore and oil drain. Whether you are running water or oil-cooled heads, this kit provides the essential components to service one complete engine. It is a robust solution for mechanics who demand precision fitment and high-temperature resistance in their custom performance projects.
Manufacturer part number: C10193-HB.
