PRESS IN STUDS QUESTION

got a set of 69 302 heads with pressed in studs. mine have a hole drilled through the head and through the stud. is this factory, or somebody trying to make press in studs stay in the heads better.

Somebody trying to keep the studs in the heads. Not factory.

The early SB Chevys had a habit of pulling the studs out of the head. A common fix was to drill the stud and stud boss to insert a piece of drill rod to act as a lock. Not the best solution, but it worked. Regards. John--Las Vegas.

It's called "pinning the studs". It works fine for keeping the studs from pulling out, but removal is a PITA if the studs break.

Good Luck!

it's because factory studs by themselves can't handle higher spring pressures. The springes will actually pull the studs up. Cheap way to not put the studs and thread them for threaded studs.

thanks for the info fellas. im just going to get rid of the heads. i have a set of e7te heads ill use instead. thanks again.
