Bolt stretch and head gasket loading are more even across the entire cylinder head when this procedure is followed. Helps prevent head gasket failures. Also, using the correct lube on the bolts is critical.

I'm curious why the cylinder head bolts needs to be completely tightened, loosened and retightened during assembly?
For me this procudere is different than from other (CAT) engines.
