If they are 1/2 inch heads, torque should be about 225 inch pounds. If they are 9/16 heads I think it is up around 280 inch pounds in at least two steps. If it is a new head gasket, re torque after about 1/2 hour running.

Is there a sequence that has to be followed and can you use the same bolts?
Thanks

Is there a pattern that has to be followed when torqueing the head bolts?

Thanks
