Frequently Asked Questions
What's included in this two-pack?
Two complete head and base gasket sets — enough for one full engine rebuild or two partial rebuilds.
Will this fit overbored EVO Sportsters?
No — this gasket is spec'd for stock bore only. Overbored engines require a different part number.
Do I need to replace both gaskets at once?
Yes — head and base gaskets should always be replaced together during any bottom-end service to ensure a proper seal.
Is this a direct OEM replacement?
Yes — Cometic manufactures this to match original Harley-Davidson specifications for EVO Sportster engines.

DONT FOLLOW PRINTED INSTRUCTIONS!
DON’T FOLLOW THE INSTRUCTIONS ON THE BOX!!! It says recommended torque is 42 lb/ft. You know what happened at 32lb/ft? One of bolts broke! And I was lucky there was long enough piece sticking out to remove it without drilling out! Check photos.

No leaks!!<br />Ordering was a breeze. Shipping was fast and I live way out in the middle of the Pacific Ocean, Hawaii. Price was much better than competition.
