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

We were shifting it a 8000 but I have seen the recall at 9300 max a couple times after some serious burnouts. The reason for bottoming the stud with your fingers is so when you put the nut on it stays indexed and keeps the groove lined up.
As per ARP instructions is if the stud goes in the hole to far and the nut doesn't get full engagement on the threads. They want you to drop a ball bearing in the hole and bottom it on a bearing. So turning the stud out? I don't know. But I will ask them.



so again please tell us how fast this monster is. I gotta know.
