Frequently Asked Questions

Will this fit my Twin Cam engine?

Yes — this is the OEM-replacement head gasket for all Twin Cam engines. Verify your engine displacement to confirm compatibility.

Why is this sold in a 2-pack?

Two gaskets allow for a complete top-end rebuild or inventory for shops. Single gaskets are typically needed per engine.

What thickness do I need?

This .040" thickness is the standard OEM spec for Twin Cam engines. Do not substitute thicker or thinner gaskets without engine mapping adjustments.

Do I need to replace both gaskets during rebuild?

Yes — replace both cylinder head gaskets during a top-end rebuild to ensure even compression and prevent leaks.
