An old hand at the shop told me I was torquing head bolts wrong for years
Been doing heads on 6.7 Cummins motors for about 5 years now, always went to the final torque in one smooth pull. This crusty mechanic watched me one day and said I was crushing the gasket, told me to do it in three stages instead. Has anyone else had their method totally wrecked by some old timer's advice?

Torqued head bolts in one pull for 10 years on Duramax motors, never had a gasket fail.

Wait, are you torquing them dry or with some kind of lube on the threads? I've always used a little oil on mine and never had issues either.
