Hey guys i know this is a dumb question just bear with me... I've had what i thought was a complete roller rocker set sitting in my bedroom for a few months and finally got the time yesterday to try to install them. I got the valve cover off and the first two rockers off no problem, but when i looked at the new rocker i was about to put on something didnt add up. It could just be that im not that engine savvy as of yet when it comes to putting theory to work but i think im missing something...heres what ive got:

and some close up pics of the bolt or stud or whatever it is (im a little confused and frustrated right now)

different angle

another angle

sorry the pics are somewhat blurry took the picture with a phone... i think i prolly asked a stupid question but i couldnt find any answers anywhere (Only thing i could find was install for a viper and for some 8 cylinder truck that looked like it was using spacers). Anyway help is greatly appreciated

your missing the rocker studs.

That thing you're holding in your hand looks to be the posi-lock nut. When you set your valve lash you get the nut where it needs to be, then tighten the set screw which puts prssure on the top of the stud to hold it in place. But you also need to get new studs, like Phlatcav said. You need studs from a 2.8 V6. I can't remember which year engine I got mine for but it was an early 90's. They have the proper M10 threads to mount in the head, but have the 3/8" threads to mount your rockers. You'll also have to open up your valve guides so the pushrods don't bind.

sweet guys... thank you soo much. Yeah i knew about the valve guides but i didnt realize i was missing anything til yesterday. I'll start looking for the studs, but if anyone has part numbers thats cool too. Again, thanks a ton guys, i was about to send the things back before i realized they were a perfect fit just looked like i was missing the stud (now that i know what im missing). Thanks guys.

part number: 88419-12 Chevrolet 60° 3/8 top, 10mm bottom, for chevy v6 (2.8-3.1L)... im pretty sure thats right, just in case anyone else needs the info later.
IF NOT, please someone correct me cause im going to buy them in a couple days, and id hate to screw anyone else over too.

by the way thats crowers part number

Not sure about the part number but the description is right. I got mine for like $10 at the local junkyard so I couldn't tell ya lol.

yeah autozone wants like $2 a piece for them, and crower wants like $90 for a set so ima prolly go with the autozone stuff since theres are clevite anyway. thanks man.

You open up the pushrod guides, NOT THE VALVE GUIDES...that would be bad lol.
Also, the V6 rocker studs are for the magnum rocker conversion only, the threading is not correct for the polylocks on the aluminum rockers you have.
You need the expensive rocker studs, sorry.



fortune cookie say:
better a delay than a disaster.

You've got a 2000 2200, you'll need the 8mm base, not the 10mm base studs. The ARP part numbers are 134-7201 (for a set of 16) or 134-7221 (for the 2 pack). They are available through Summit Racing or Jegg's (you may have to special order them, but it doesn't take long through either company.)

Note you may run into valve cover clearance problemswhich will require grinding portions of the valve cove and/or the purchise of shorter/smaller poly-locks. See this link for ginding info.

So then they will work madjack? Thanks guys.

i have these studs which were for a V8, so i still have half. if your interested PM me. http://store.summitracing.com/partdetail.asp?autofilter=1&part=ARP%2D134%2D7201&N=115&autoview=sku

Yesterday was a bad day for me. I would sit down to type something, and my niece would start in on something and I'd type sh!t all wrong. I dind't even catch that before I posted it and I don't have an edit button anymore.

LOL... youre good i knew what you were talkin about man.

Pauli youve got mail

Bringing this back to the top:



Anyone want to go half with me on a set of Proform rockers (Link) and ARP studs (Link) for a 98-up 2200 (Metric studs and no pushrod guides)? It'll be about $135 for your half, it's $266 for the V8 set from Summit

i have half of that set already, no studs though. $60 for the rockers if you want them.

OK, let me ask you... is it worth it? can you tell a difference at all, or is it basically something to do so that you can say "I did it"?

i never got them installed. right after i bought them i decided on doing an eco swap

so the ones you have are the same ones in the link I posted? if so, send me a bill on paypal to ebrown0104@hotmail.com

they are the exact ones. bill sent.

I'd go half for some studs. PM me if you're interested.

I am going to pay you for them, I just have a few items on eBay for sale right now, and I want to wait until I get that cash in my Paypal account. I didn't forget
