My nervous mechanic found an instruction to retorque a 120 before valve adjusting, that made us comfortable doing it.
I`m sure there is a thread on this which said never retorque a 135. I`m guessing a stud could snap,that`s no fun. But if you had the head off a 135 you have to retorque. Surely you don`t need to change the studs if you pull a 135 head? Maybe you do.
