Common questions
Will this head gasket work on Twin Cam or older Harley engines?
No, this S&S Cycle head gasket is designed specifically for 2017 and newer Milwaukee-Eight (M8) engines. Twin Cam and older Evolution engines require different gasket specifications.
Is this an OEM Harley-Davidson gasket?
No, this is an S&S Cycle aftermarket gasket engineered for S&S M8 applications and high-performance builds. We recommend verifying compatibility with S&S if you are using it with a non-S&S M8 build.
Do I need to replace both head gaskets at once?
It is strongly recommended to replace both head gaskets as a pair during any top-end engine work to ensure consistent compression and sealing across both cylinders.
