Product Overview
Low compression, combustion leakage at a head gasket, carbon buildup, or valve service on an opposed-twin Onan requires new head sealing parts before reassembly. This set provides two head gaskets and valve-grind gasket pieces for servicing both cylinders.
Head gaskets do not correct warped heads, pulled threads, worn guides, burned valves, or overheating causes. Check the engine model/spec, head flatness, valve condition, cooling fins, and torque sequence before installation.

Frequently Asked Questions
Q: Will new gaskets fix a warped cylinder head? A: No. Both heads and block surfaces must be checked and corrected if they are outside flatness limits.
Q: Why are two head gaskets included? A: The listed Onan engines are opposed twins with one cylinder head and head gasket on each side.
Q: What should I compare before ordering? A: Match engine model/spec, opposed-twin head design, 110-3181 gasket shape, bore openings, bolt pattern, and valve-grind gasket pieces.
Q: Is this supplied by the original equipment manufacturer? A: No. This is a new aftermarket part. Brand names and reference numbers identify fitment only.
Package note: The set includes two head gaskets and the valve-grind gasket pieces shown; valves, seals, guides, and fasteners are not included unless pictured.
