Frequently Asked Questions
What's included in this 2-pack?
Two complete head and base gasket sets — one pair per engine rebuild or spare set for future service.
Will this fit my EVO with big bore pistons?
No — this part number is for standard bore only. Big bore engines require a different gasket set.
Is this the same as OEM Harley gasket #16664-86b?
Yes — Cometic manufactures this as a direct OEM-equivalent replacement to Harley part #16664-86b.

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.
