327 rocker arm stud question

[Michael G.]

Are the rocker arm studs on a 63 small block threaded into the head, pressed in, or what? If they're threaded in, do they have some sort of locking feature?

Thanks, Mike

pressed in, no locking feature, they can come out with to much spring pressure or too radical a cam
