Frequently Asked Questions

What is a tappet block gasket and why do I need it?

The tappet block gasket seals the valve cover to the cylinder head on Panhead and Shovelhead engines. It prevents oil leaks around the rocker box area.

Why buy a 5-pack instead of a single gasket?

Five-packs are designed for shops, fleet owners, or riders rebuilding multiple motors who want spares on hand.

Is this foam or cork?

This is a foam gasket, which provides better sealing and durability than traditional cork on older V-twin engines.

Will this fit my Twin Cam or Milwaukee-Eight?

No — this gasket is specific to Panhead and Shovelhead engines. Twin Cam and M8 engines require different part numbers.
