NOTE: The cylinder head bolts are tightened using a torque plus angle procedure. The bolts must be examined BEFORE reuse. If the threads are necked down the bolts must be replaced

Necking can be checked by holding a straight edge against the threads (3). If all the threads do not contact the scale (2), the bolt must be replaced.

CAUTION: When cleaning cylinder head and cylinder block surfaces, DO NOT use a metal scraper because the surfaces could be cut or ground. Use ONLY a wooden or plastic scraper.

Clean sealing surfaces of cylinder head and block (Refer to ENGINE - STANDARD PROCEDURE) .
Install new head gasket over locating dowels.
Install cylinder head to block, assuring head is properly positioned over locating dowels.
