Frequently Asked Questions
How many gaskets are in this pack?
Two complete head and base gasket sets — one for a full rebuild or one spare for future service.
Will this fit my big-bore Sportster?
No — this is for stock bore only. Big-bore and stroker motors require a different thickness. Verify your bore size before ordering.
Do I need new bolts too?
Gaskets alone do not include head bolts. Check if your bolt set is reusable or if you need fresh studs for torque-to-yield applications.
What's the thickness?
.040 inches, designed for stock EVO Sportster bore. Do not use on overbored 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.
