Head Bolt Reuse/Replace
EXAMINING CYLINDER HEAD BOLTS NOTE: The
cylinder head bolts should be examined BEFORE reuse. If the threads are necked down, the bolt(s) should be replaced.
Necking can be checked by holding a scale or straight edge against the threads. If all the threads do not contact the scale, the bolt(s) should be replaced.
