Frequently Asked Questions
How many gaskets are in a pack?
Two head gaskets per pack — enough for one complete head service with a spare.
Will this fit my Harley with M8 engine?
This part is for Twin Cam engines. Milwaukee-Eight (M8) engines require a different bore-specific gasket.
Do I need to retorque the head after installation?
Yes — follow your engine manual's head bolt torque sequence and specs after installation. Improper torque can cause leaks.

Proceed with caution
Cosmetic rocker box gaskets leak on chrome twin cam covers. May work fine on standard covers.
