LA small block,Do you put an oil passage in your head stud?

I can't even answer you. Because you make up stories to make yourself right. These are not stretch studs. There is no way you are stretching the shaft on the stud before you rip the threads off . Just look at the Diameter and compare to the inside of the last 1/2 13 thread. And then think of what you are saying. Stretch stud? LMFAO
You cant answer me because you dont even understand how and why a bolt OR stud stays tight. @Bakerlite even posted DIRECTLY from ARP the correct information, but your too upset and angry to comprehend what many of us are trying to tell you. Your pitching a tantrum, over something you dont understand, claiming I'm "making up stories" all because your upset people see through your charade of "We are the best! Take our advice" My son knows more than any of you!! Sheesh
