Default which rocker studs

ARP P/N 100-1701 has a 1.90 effective stud length.

ARP P/N 134-7103 has a 1.77 effective stud length.

Which ones do I need?

7/16 NSA Comp Ultra Pro Mag Rocker Arms

Patriot Dual Gold springs

GMPP or TFS guideplates

5-16 Pushrods

Stock Lifters

Just to state everything I'll be using.

1.77 is what you need. I think the 1.9 are for big blocks

134-7103 (1.77") is what I use with my comp pro mags without issue. Go with TFS guideplates, that's what I did.

Thanks guys I'm going to order the shorter ones, and TF guideplates just to be sure. I already have the GMPP's but getting mixed signals on them so I'll just hang on to em or sell em if someone wants to try them.

Jegs. Theyre backordered a couple weeks from summit. Jegs said "ships today" so I went with them. Ended up getting everything but gaskets and guideplates from jegs. Got those from summit and the timing chain from gmpartsdirect.com

I got the "Ultra" pro mags, that would be the difference.

You shouldn't need anything longer than 1.77 with stock head castings and stock-length pushrods.

I went with ARP's Pro Series 1.90 for more poly-lock thread engagement.

I agree on swapping for the ultras. I think the price is close or a littlw cheaper and they look pretty badass on paper.

W the trouble a few have started having w pro mags I'm glad I went we the ultras.

I think a good lightweight, ridgid valvetrain benefits any setup.

The Ultras also have a lifetime warranty.
