You're going to need hardened push rods too.

I guess some earlier Lts have the hardened push rods, so I will leave that up to those who know.

I found the seals part numbers.
Assuming the 95 push rods are hardened,anything else I should purchase for the install?

The seals are cheap. Replace them. Besides, might have some that got old and whatever.

93-95 LT1 F-bodies have hardened pushrods from the factory.

Re: When installing 1.6 roller rockers

Price the seals at your local auto parts store, they are not expensive and you won't have to pay shipping.
You didn't say which guideplates you have. You want the GMPP ones. A search will turn up the part number if you need it.

Re: When installing 1.6 roller rockers

Probably need rocker studs that are longer for the guideplates otherwise they won't be threaded into the head as far. Be sure not to knick the seals when installing them.

Re: When installing 1.6 roller rockers

Got the full set of seals from Oreillys for $17.00.
Got the 7/16 CCs studs.
Actually I still need to get the guide plates but they will be the GM plates from SPDC.

I bought a valve compression lever, the one that looks like a small crowbar. I know I cant use this on the rear most valves but my question is how many of the valves will this tool work on. I will get the small screw down kind for the hard to reach ones but we all know what a pain in the wrist it can be.

Re: When installing 1.6 roller rockers

There is one screw type that you can take off the handle and use a wrench on it. I got it at Napa.
