I have CC 7/16 1.6 nsa rockers so I need to use gm guide plates. I want to use arp rocker studs. Which part# would be the correct one to use with guide plates. Should I be concerned about compensating for the amount of thread that will not be fastened to the stud bosses due to the guide plates or is it insignificant?
Bottom line is, what rocker studs should I be using.

 

I don't have the part number but the amount on stud length you lose going through the guideplate is not significant. Go to the Comp Cams website for the part number.

 

I used the ARP 7/16" studs and GM guideplates w/ 1.7 roller rockers. No problems here, and that's w/ multiple times in the 6300 rpm range, and a few 6500 rev limiter bounces.

 

How about pushrods? I know I will need hardened but can I still use the stock length.
Can anybody give me a part # for the correct pushrod?
