LT4 rocker arm studs
Do the stock GM heads have heli coil inserts for the rocker arm studs?
Reason I am asking is that I have a set of bare LT4 castings, and the standard 7/16 base rocker studs just fall in the holes. They appear to be around 1/2" threads. Before I order the GM 12552126 studs, I wanted to make sure they just don't need some heli coils installed.
Just never delt with GM bare castings before!
