Roller Rocker, Valve spring install

[Vettefan87]

You have to take the heads off to remove the valve springs right? But do you have to remove them to put roller rockers on too?

No to both questions.

There are adaptors that screw into the spark plug hole and allow you to attach an air line. With the valves closed, air pressure will hold the valves in place after you compress the springs and pull the valve keepers. There are also valve spring compressors that will allow one to do it this way.

Rocker arms simply need adjustment when replacing them.

Some auto parts stores such as Murrays have tool loaner programs. They would probably have the valve spring compressor for loan.

Thanks guys, the buddy of mine with the Turbo TA was telling me that it wouldnt be worth it, and that I would have to pull the heads. I think he might be getting a little worried

Ok with the advice of Moonunit he said go with Comp Cames Pro Magnum rockers, part number CCA-1318-16. Anybody know what kind of valve springs I should go with???

I use comp cam's bee hive springs.
Can't bind and lots of tention ,no floating at high rpm's.

It depends on what ratio rockers you get. With the original 1.5 ratio, your springs should be ok, unless you want to change them simply because of their age. If you buy the 1.6 ratio rockers, you will need to upgrade springs as the stock ones may reach coil bind, and that would result in disaster. Comp cams, as well as GM, have newly designed "conical" springs that are larger on the bottom than the top, which allows for tighter compresswion. An added inheritant feature is that they are slightly lighter (with the cap being smaller also), and that can help increase RPMs slightly. The only thing that may prevent the use of Comp Cams version (they call their
version "beehive" springs) part #26120, is that the outside diameter is 1.445" so you would need to check the spring pocket on your heads. I don't recall the diameter of GM's, maybe someone else does. Hope this helps. I am think of doing the same upgrade to my 89 L98, so if you have success, please let me know. Good luck.

What diameter springs would I need with 1.6 Roller Rockers?

No one ever complements the guy that gave more information.
You did great!
I was lazzy and you picked up the thread.
I used stock springs and they gouged out the RR from the pushrod to the forkrum.
I went with the bee hive spring to get the clearence.The titanium retainer and smaller spring gave me the clearence.
All they are is an LS1 spring,but they fit.
