Almost identical to OEM. Good fit. I did miss that they are sold as each and not as a pair. Small detail and my fault but it did slow my project down a bit.

Frequently Asked Questions
Is this a complete gasket kit or just the base gasket?
This is the base gasket only. Cometic also offers complete EST gasket kits that include head gaskets, valve stem seals, and all hardware.
Will this fit Twin Cam or other Harley engines?
No — this part is specific to Milwaukee-Eight (M8) engines. Twin Cam and other V-twins require different part numbers.
What does the Gen2 embossing do?
The pressure relief embossing improves sealing performance and helps manage combustion pressure in modern M8 engines.
Do I need special tools to install this?
Base gasket installation requires basic engine disassembly. Torque specifications from your service manual are recommended for proper sealing.
