Frequently Asked Questions
What gaskets are included in this kit?
The complete set covers all engine gasket locations — heads, cylinders, covers, and seals needed for a full rebuild without ordering individual parts.
Do I need anything else for an engine rebuild?
This kit covers gaskets and seals only. You will still need bearings, rings, and internal engine components depending on your rebuild scope.
Will this fit my Milwaukee-Eight engine?
No — this kit is for Twin Cam engines only. Milwaukee-Eight (M8) engines require a different gasket kit.
Can I use individual gaskets instead of the full kit?
Yes. Cometic sells individual gasket part numbers if you only need specific seals rather than the complete kit.

Works Fine at a lower cost
I usually have an OEM from Harley Davidson, I have used this twice on my 04 Electraglide, no leaks or issues. At a much lower price.

A mediocre gasket
I didn’t use this gasket after removing the derby and seeing the Harley gasket that I removed. No comparison in quality. I ended up going to the local dealer and bought an O.E. gasket.

There is nothing on them indicating they are actually Cometic gaskets. Are they Substitutes?
