1970 390 Heads...ARP 7/16 Rocker stud..What is part Number.?

[jeepmonster]

Anyone know the part number for AMC ARP 7/16" rocker studs??? I am going to use 1970 390 Doglegs on my 343, I am getting them for $100 and they are very low mileage and complete and have been sitting on a rack in a mchine shop for a LONG time wasting away..so I thought I'd put them to use for my 343 buildup. They are 291C and are complete but I will probably be using the new valves that were in my 343 square port heads. Really need to find the part number for the ARP 7/16" rocker studs first. Thanks. I'll be using Harland Sharp roller rockers as well and titaniu, retainers with 10 deg locks.

I think they are big block chevy studs

On my AMX I used ARP # 134-7104. Those are 7/16 into the head, and 3/8 on the top.

# 100-7101 are about the same with 7/16 on both ends.

I have '70 model dog leg heads on a 343 block
and am using the 7/16 Crane Hi-Energy shiney cast roller rockers.
I found the "standard" length replacement Rocker Studs to be a little short,
and replaced them with Moroso #67820 to get good poly lock thread engagement.
Moroso #67810 is for big block chebbie, and has 1-3/4" stud above head.
Moroso #67820 is for Ford Boss302/351 and has 1-15/16 " above head.
The Poly Locks I had were not threaded all the way down to the bottom
and to get good poly lock to stud tread engagement I needed that 3/16"
Not sure what the ARP part numbers are.
