I've gone thru some old posts and am still as confused as when I started.

I'm putting together a RAV and trying to narrow down stud selections.
I will be using Comp Cams Gold Rockers, stock RAV guide plates, Jomar stud girdles and Milodon tall valve covers. The engine is being built for a bracket car.

In a 2016 post regarding stud girdles and stud lengths, Tom V made mention regarding a Ford Boss 351 stud from Ford Motorsports with .750" screw-in thread depth with a 2.625" installed height from the bottom of the hex to the top of the stud. I'm not able to locate an exact match to those specs. I even tried the Ford Performance website, but no mention of rocker arm studs.

In my search so far, I found the following & I think one of these is what I'm looking for, but I need some good input from the forum.........

ARP KIT 100-7101 (SMALL BLOCK FORD)
INSTALLED HEIGHT: 1.90"
ADJUSTABLE THREAD LENGTH: 1.00"
SCREW-IN DEPTH: .750"

ARP KIT 135-7202 (CHEVY BIG BLOCK)
INSTALLED HEIGHT: 2.35"
ADJUSTABLE THREAD LENGTH: .850"
SCREW-IN DEPTH: .850"

ARP KIT 334-7204 (CHEVY BIG BLOCK)
INSTALLED HEIGHT: 2.00"
ADJUSTABLE THREAD LENGTH: .800"
SCREW-IN DEPTH: .750"

ARP KIT 334-7203 (CHEVY BIG BLOCK)
INSTALLED HEIGHT: 2.100"
ADJUSTABLE THREAD LENGTH: .800"
SCREW-IN DEPTH: .750"

Like most, I want to make sure I have enough of stud at the top to make sure the rocker is secure with polylocks using the stud girdles mentioned.
