Default Rocker Studs
What size rocker studs do I need for a set of World Windsor Sr. heads?

I know the threads are 3/8" but I need to find the right height studs for use with my rockers.

I bought the heads used and the rocker studs had been removed.

you can run a 3/8 stud or the 7/16 stud what rockers do you have ? what do they take? I would run the 7/16 just for the shear strength over the 3/8 unless you already have 3/8 rockers.

well, you cant just go randomly drilling them out. If you do, and you dont get it perfectly center, you will NEVER get the rockers to line up properly... as is the case right now with my heads...

heres a pic... maybe this will help you understand!
look at the left stud bosses
