A couple of posts saying to use the shorter 134-7103 for stock valvetrain.

I used the 100-7101 on my 421 with Crower roller rockers. Perhaps they’ll also work for you as well, I’m using stock valve covers with a thicker 5/16” gasket for polylock clearance.

Okay, I'll go with those. Virtually identical length as the stock studs at 2.45", slightly less screw-in depth (.70, not .75) but put in with moly or Loctite they should sit firm enough. Rocker nuts will be the 300-8242's.

What is the specific moly product ARP recommends for rocker studs? I'm not seeing anything on their site.
