Cylinder head disassembly and inspection procedures should be performed by a qualified automotive machine shop. Installation: Clean the gasket mating surfaces of the cylinder heads and crankcase with lacquer thinner or acetone. They must be clean and oil-free. Install the cylinder head gasket onto the cylinder head locating dowels on the engine block. Install the cylinder head(s).
