Are these going to work with my LT1 heads?

I ordered them through my local shop because I saw somewhere they would but according to summit they only work on motors up to 1986. Do they state this just because they are NSA rockers?

 

your link doesnt work,, but you need self aligning rockers for stock lt1 heads,, in order to use non self alinging rockers you need to convert over to guide plates and hardened pushrods

 

As stated above link doesn't work...
But if they say there NSA Non-self aligning.. You WILL need guideplates..
I have some for sale..

 

are the 94 pushrods hardened?

 

Yes they are suppose to be.. But you can pick up a set from Comp for like $30 bucks.. Its cheap insurance..

 

so with guideplates these will work right? That is why they are stated not to fit the newer heads because they are NSA?

Don't forget you'll need guideplates aswell..

 

correct, they need to be narrow body as well(to clear the VC bolts)

 

YES with guideplates they will work..
I have a set of GM guideplates for sale..

 

If you cut out the supports inside the valve cover. You can fit the wide ones just fine.. I did this aswell for my Comp Pro Mag NSA rockers..

 

I ordered the GMPP from scoggin dickey already so thanks anyways

 

Cool.. No problem.. Good luck with the install..

 

thanks...

 

I'd be a little leary about buying those. A person I knew from another board bought something similar to those (NSA) and because the rocker body was so huge they bottomed out on the hex part of the studs, pulled two studs out of the heads, all the rockers were gouged where it made contact on the studs, bent the pushrods from the two studs that were pulled out and most of the other pushrods were eaten from being pushed into the guideplates. He didn't know a whole lot and had a shop install them who of course didn't know WTF they were doing.
If you are going to go with those make sure to check the rocker body to stud clearence.

 

Sounds like a combination of the wrongs parts.. And shop that didn't know what they were doing like you said.. Any small block chevy rocker will work, just refer to my post above about cutting the vavle cover supports.
