Cometic 2017 Harley-Davidson Milwaukee 8 3.937in Top End Kit w/ Cam Change .040 Head Gasket

This Cometic top end kit is built for the 2017 Harley-Davidson Milwaukee 8 engine, specifically when you're changing out the camshaft. The kit includes a .040 inch thick head gasket, which is a common choice for mild performance upgrades or when dealing with slightly different compression ratios after a cam swap. Cometic is known for using quality materials, and this kit is no different, aiming to provide a solid seal for your engine's top end.

The .040 head gasket is a key component here. It's thicker than stock, which can help to slightly lower the compression ratio, making it a good match for many aftermarket cams that might increase overlap or duration. This helps prevent detonation and keeps the engine running smoothly. The kit is designed to fit the Milwaukee 8's 3.937-inch bore, ensuring a proper seal around the cylinder. When you're diving into your engine for a cam upgrade, having a well-made gasket set like this is crucial for a reliable rebuild.

Make sure to follow the manufacturer's installation instructions carefully, especially regarding torque sequences and any specific preparation needed for the cylinder head and cylinder deck surfaces. This kit is a solid option for Milwaukee 8 owners looking to perform a cam change with confidence.
