While getting ready to install my new 7/16 ARP rocker studs, I read the instructions to check for correct torque spec. While reading, it specifies to use ARP moly lube when installing.

Should I use any type of sealer or lube when installing these studs into the heads? I have bone stock heads.

I have the following to use if needed : ARP thread sealer, GM NPT paste and Permatex #2. I have others, but figured these would be the best to choose from. Any help is appreciated.

 

just get some pipe thread sealer permatex PTS, you really only need it on the intakes.

I always tq mine to 50#

 

Now it looks like the rocker studs are too long. I should have known things were going too well. I bought the Pro Series studs that are meant for roller rockers part # 234-7206.

Does anybody know the correct part # for the Pro Series 7/16 studs that I need? Is it 234-7202?

 

The max lenth the threads can be is .5" with guideplates but I think you
already found this out.

Whatever you do DON'T use the ARP sealant!!!!!

I repeat, DON'T use the ARP sealant on rocker studs!!!!!

Even though this applies to ported heads, it's good general practice to
use Permatex #2, GM sealant or other appropriate sealant for all rocker studs.
