Frequently Asked Questions

How many gaskets are in this pack?

Two complete head and base gasket sets — enough for one engine rebuild with a spare.

Is this the OEM Harley gasket?

Cometic manufactures this to OEM spec as a direct replacement for Harley part 16774-86D.

Will this fit my Twin Cam or M8 Sportster?
