Default Correct part# for 7/16 ARP Rocker Stud for LT4 head

What is the correct ARP rocker stud for the lt4 head?

I want 7/16 base thread and 7/16 on top.
This will be for Non self aligning rockers with guide plates.
I do not know the correct stud heights/depths and I have read that there can be a clearance issue with incorrect length studs so...


What is the best 7/16 rocker stud for a LT4 head with NSA rockers and GP's

They are BBC rocker studs. I'm feeling too lazy to look them up.

OP, what rockers are you running BTW? I'm considering upgrading my LT4 rockers as well. Apparently you have to run 'narrow body' units.
