Im switching to NSA rockers this winter with the GMPP guideplates, is the stock rocker going to have enough thread in it to screw into the head? if not, which 3/8 studs should I buy... part numbers if you guys could help me, thanks alot.

If switching anyway just go to 7/16 rockers.
Also do not use the GMPP guideplates, they are better than the regular aftermarket stuff as far as alignment goes but they are not really RIGHT.
I was running and recommending the GMPP ones till I found mine worn , granted it was 9K miles or something on them but I switched to Isky adjustable and those are right once you adjust them.

I already have the rockers and plates, i think ill try them, the car only sees maybe 2000 street miles a year, and i was a little worried about how difficult it is too adjust the iskys. but my question is if ither the studs comp or ARP make are a longer thread area that goes into the head?

i'm also interested in this. i did the same thing and bought 3/8 rockers not thinking.

Since I have a new ARP set laying by my desk, I measured them. The lower threaded portion of the ARP #134-7103 stud is 5/8" long. That's the part number for the stud for 7/16" rockers on small block heads and I suspect that dimension for 3/8" studs would be the same. The big block stud will work but the upper threaded portion is too long and results in the rocker pivoting on the threaded area instead of the solid shank area of the stud.
