Every gasket needed for top end was in the kit, very good quality.
The kit came with all the gaskets
By David F. on
Verified Purchaser
The kit came with all the gaskets you need to do a quality top end rebuild plus torque instructions for the heads, the only thing you could whine about is it would have been nice to have had a gear chest gasket, but I guess that's not top end.

Cometic Top End
By Mike on
Verified Purchaser
Bought Cometic gaskets to replace factory Harley Davidson cylinder base gasket. Good quality you would expect from Cometic and all gaskets needed for a top end rebuild were included. Fast shipping and good service and excellent price from Parts Giant.

Questions & Answers
Does it come with a list for what all the rubber o rings are for

Every Cometic gasket kit comes with a placard that indicates what's to be included within the box. Sometimes, OEM numbers are also included on that card. And with that information, you should be able to determine what gaskets are appropriate for servicing your machine.
does this kit include the valve seal
