Frequently Asked Questions

Is this for Twin CAM or Milwaukee-Eight engines?

Twin CAM only. Milwaukee-Eight (M8) engines require a different Cometic part number.

Why are these sold in pairs?

Twin CAM engines have two cylinder heads, so a 2-pack covers both gaskets for one complete overhaul.

What thickness is this gasket?

0.030" compressed thickness, matched to Twin CAM head specifications.

Do I need a new gasket for an engine rebuild?

Yes. Head gaskets should always be replaced during engine teardown or top-end service to ensure a proper seal.
