is it ok to run the stock studs with guideplates or should i get new studs? going to upgrade to 1.6 nsa roller rockers. i dont think i will be spinning anything past 6300rpm.

If you haven't already purchased the rockers go with a 7/16" stud. That way you're set for any additional upgrades.

thats one way of saying i should get new studs

another question; i was looking at guide plates on summit and i noticed it says machining required.... you have to machine your heads to use these? 0.o

and yet another question ... raised or flat guide plates?

Definitely add 7/16 studs 7/16 roller rockers.

Use these - Trick Flow 30400623-8. These fit LT1s with no modification.

OP, you still have to get studs for use with guide plates. Your stock studs only have about 6 threads on them. Using guide plates take away about 3 threads. So then you must have the correct studs to make up for the plates.

But if not planning on turning high rpms, stay SA. A good SA rocker will hold up fine.

after i posted i thought i remembered a thread about this but better to ask then to find out the hard way...

thanks for the part number ramair

what stud should i get? I want a 3/8 stud.

BOOSTED AFR

Standard length ARP small block Chevy studs will do you fine.

Why are you so set on a 3/8" stud? 7/16" studs and rockers are very similar if not exactly the same price and they make for a more stable valvetrain.

im going to run a scorpion roller rocker, they dont make a narrow body rocker with a 7/16 stud according to there website

BOOSTED AFR

Comp Cams doesn't make a narrow 7/16" either. I see your reasoning.

You don't have to use narrow body rockers.....trim your valve covers and the regular ones will fit fine. Shbox.com has pics on his site of where to trim them. (Also plenty of info on cam swaps, rocker adjustment, etc.) If you haven't bought rockers yet, I'd go 7/16". Either use the TrickFlow guideplates that RamAir mentioned, or use GM ones. Most other brands have incorrect spacing for LT1's. Use flat guideplates. You don't have to do any machining on aluminum LT1 heads.

Like someone else said....the lower threads on the stock 3/8" studs are too short when using guideplates.

sucks when you ask questions and then don't like the answers so most of the knowledgable folks give up on you. Just about everyone in this thread knew about trimming the valvecovers for standard body rockers, you just didn't want to hear anything that was not the answer you were looking for and they gave up on you.

Lets hope there won't need to be a next time

ya know, i didnt know about the standard body rockers fitting. i've done lots of searches on rockers over the last couple years and there isnt a lot of threads that specify what rockers were used other then the ratio and brand. i knew about trimming the covers i just assumed you had to do that for the narrow body rockers. its not that i didnt wanna hear it its that nobody said it. so drop the ******* additude

on a different note someone i know mentioned to me about a cradle .... i wouldnt think that would be nessesary for my little cam tho

BOOSTED AFR

Stud girdle, not cradle, and no there is no need for one until the camshaft is fairly large. Besides they require perimeter bolt valvecovers.
