Be careful not to damage the head gasket surface. After the exhaust valves and intake valves are removed, clean the valve guide bores. Use cleaning solvent to remove dirt, grease, and other deposits. Clean all bolt holes. Remove all deposits from the exhaust valves and intake valves with a fine wire brush or buffing wheel.
