Frequently Asked Questions
0.040in (1.02mm) standard thickness. Cometic offers other thicknesses like 0.030in or 0.051in - confirm for your compression ratio.
Yes, it includes the one-piece embossed steel oil pan gasket, which is a common leak point on Evo Sportsters.
Fits 1991-2003 Evolution Sportster models (post-rubberband era). Not for pre-1991 ironhead or post-2004 models.

Installation Guide
Difficulty
Medium
Est. Time
2 hr 0 min
Tools Required
- torque wrench
- socket set
- gasket scraper
- feeler gauges
- engine stand (recommended)
Pro Tips
- Apply thin layer of assembly lube to head gasket; torque in 3 stages following Harley service manual sequence; consider ARP head studs for high compression builds
Common Mistakes to Avoid
- Not cleaning mating surfaces thoroughly
- Incorrect torque sequence on head bolts
- Reusing old bolts without checking stretch
Comparison vs Stock/OEM
Cometic MLS head gasket is more durable than OEM composite; one-piece steel oil pan gasket vs. multi-piece cork OEM prone to leaks
Improvements
- Superior sealing under high heat/pressure
- Reduced blow-by in performance applications
- Longer service life
Considerations
- Requires precise torque specs; not reusable like some MLS gaskets
Durability & Warranty
Expected Lifespan
Reusable multiple times with proper torque; outlasts OEM 2-3x in performance use
Warranty
1 year manufacturer defect warranty
Maintenance
Inspect during valve adjustments; re-torque head bolts after 500 miles initial run-in
