Very simple.
1) Remove valvecovers
2) remove rockers
3) remove pushrods
4) install new pushrods after soaking in oil
5) reinstall rockers & torque to I believe 22ft/lbs(check on ls1howto.com for the correct spec)
6) reinstall vlavecovers
Your done. It's very straight forward.

Only thing i can add to this for a first timer is be careful, some of the edges on the heads are dam sharp!

Just unplug your spark plug wires from the packs, unplug the main harness for the packs & each individual pack harness, unbolt coil pack bracket & remove as (1) whole piece.
I also only use 2-3 of the bracket bolts upon reinstalling & you'll understand why after you finally get all the bolts out the first time, LOL. Using 2-3 is plenty enough to hold them on the valvecovers.

When starting camshaft install, changing valve springs, changing heads, or whatever I make sure #1 piston is at TDC of firing stroke before starting. Remove #1 sparkplug and place finger over #1 sparkplug hole. While rotating engine feel for airpressure build up at finger then continue to rotate engine until piston is at TDC of firing stroke STOP.
This proceedure was scaned from the 1998 service manual. Using cam sprocket timing marks.

I am sure several people have just torqued down rockers without following GM's procedure. I believe you will mosty hear valve tapping until lifters settle down and fill with oil.

See thats what I did also & my valvetrain is quieter than it was stock.
I just torqued them all down & then cranked the motor over by hand to make sure everything was operating properly. Haven't had a single issue yet & still no valvetrain noise after daily driving it for 2000 miles.

I once installed new lifters in a 1970 Pontiac 455 without soaking them in warm oil. I simply torqued down all rockers without following any procedure and the motor tapped like crazy on start up until lifters filled with oil.
Since your lifters are already primed and full of oil you should be OK...
