One New Aftermarket Replacement Cylinder Head Gasket Fits Allis-Chalmers Tractors
This aftermarket replacement cylinder head gasket seals the cylinder head to the engine block on Fits Allis-Chalmers (AC) tractors equipped with 201 CID and 226 CID 4-cylinder gasoline and LP engines. A properly sealing head gasket maintains compression and prevents coolant or oil from entering the combustion chamber, making it a critical component during any top-end engine rebuild or head replacement job.

- Application: 201 CID and 226 CID 4-cylinder gas/LP engines
- Head stud count: 15-stud head (required for WC and WF fitment — see serial number note below)
