I've just finished my 500 full rebuild using factory "stretch" head bolts ( not the ARP stud version..) and composite head gaskets and new sleeves from Powers. I've now put some low miles since the rebuild.

Is there a re-torque process when using these bolts?
If so what's the re-torque spec? Hot or Cold?
at what mileage after re-build?

Or are these bolts not to be re-torqued?

Stretch type bolts should not be re torqued.
