Welcome to the forum. The answer to your question is Yes. Many people have done this to late modle LT1 engines.
As long as you're in there doing that.... why not consider the LT4 Hot Cam Kit for your LT1. The kit comes with 1.6 roller rockers, matched springs & retainers as well as the hot cam itself.
This is actually an old kit that has been around for many years and is still sold. There are newer more aggressive cam profiles around but this kit of matched parts is a proven performer.
You can check it out at Summit or Jeggs or Scoggin-Dickey

If you don't go LT4 springs you can get away with 1.6 intake and 1.5 exhaust which is a good combo for the LT1. The only real gotcha to the job is you need to grind off the drip tabs on the valve covers or get new ones. If you have the carbon fiber valve covers (93-96) the drip tabs kind of shred off and it's not the best solution

I am doing the same thing myself. You can get Comp Cams cast steel full rollers, which are actually lighter and stronger than aluminum. There are now better springs available than "LT4" springs. Technology has marched on since the kits were developed. Some folks are now using springs from the LS series of motors, springs with oval wires etc.
As far as the drip tabs are concerned, you will need (just like I will need) to actually pull the covers and look inside. After all, the LT4 motors used composite covers and used 1.6 rollers. So look inside your valve cover and see what is there before plotting a course of action.
I assume you are going to use one of the screw in air plugs to pump the cylinder up and hold up the valve ?

i have a '96 and I'm installing Lunati VooDoo 1.6 rockers. Are you saying I'm OK with my valve covers or will the tabs need to be cut
