Default Re: Head Re-torgueing - Hot or Cold?

ok i will put my 2 cents worth in, when torquing head hot your torquing an engine that has expanded metal, metal gets hot it expands, so when it cools it contracts so when that happens you lose torque value, if you torqued the head to 55# hot, and the the heads contracts when cold you will no longer have 55# torque
