Rocker Shaft Bolts

Is there a company that makes bolts for the rocker shafts? I know TA Performance makes studs but I'm looking for bolt replacements.

If they measure 1.5" long, and they are 5/16-18 thread, ARP 651-1500 is what I used on a 3.8 with stock rocker shafts.

Just get a grade 8 bolt and it'll be fine. You don't need any 'custom turbo Buick' bolts there.

I will strongly recommend some rocker saddles though. As you've seen with your own experience it's not a good idea to have the bolt touching the shaft in two small points instead of holding the shaft itself.

Grade 8 or lamaloy bolts as mentioned

ARP rates their bolts as having more tensile strength than grade 8, but grade 8 works fine if you can get them locally.
