Includes Sleeves, Pistons, Pins, Rings, Rod Brgs, Main Brgs, Sleeve “O” Rings, Full Gasket Set with the CORRECT HEAD GASKET!!, Front & Rear Crank seals.

If you need less than a full kit, please contact us. Don’t be fooled by “1 glove fits all” aftermarket suppliers, they will not be supplying the correct head gasket for this engine, as ALL aftermarket kits furnish the wrong head gasket for the small flange, and after 10 – 20 hours of use, it will blow.
