INSTALLATION
1. Clean all surfaces of cylinder block and cylinder heads.
2. Install new gaskets on cylinder block Fig. 9. The Cylinder head bolts are torqued using the torque yield method, they should be examined
BEFORE reuse. If the threads are necked down, the bolts should be replaced Fig. 10. 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 should be replaced.
