I've never heard of roller rockers
Do you mean rocker rails? Those are the aluminum reinforcing strips that run along under the rocker panels below the doors. They protect the panels from grounding especially on lowered cars.

Elite Engineering also has a sweet design.

Roller rockers are rocker arms. Roller rockers is short for roller rocker arms. They are called roller rockers since they pivot on roller bearings. They reduce friction and therefore they increase horsepower over non-roller type rocker arms.
In addition to this, the rocker arms can have roller tips that roll over the value tips instead of scrubbing them.
In case you're wondering, all LSX engines have roller rocker arms with roller tips. They also use roller lifters with the camshaft.

Yes there are better quality roller rocker arms than came with the LS1, but I seriously doubt you would notice much if any difference changing them out.

LS1, LS2, LS6 and LS7 motors do NOT come with roller tipped rockers.

not sure if you've ever checked this site out, but it's good on explaining the workings of the various engine components:

it shows the rocker arms and what they do. check out the pushrod engine at the bottom

The LT4 engine came with full roller rocker arms provided by Crane and stamped with the Bowtie emblem. The roller rocker design enables higher revs with less heat and friction.
The stock stamped rocker arms on the LT1 were 1.5 where the LT4 came stock with 1.6. The reason to go larger or longer is an old cheater trick - the higher lift, the longer the valves stay open and/or closed adding a few extra ponies. The only concern is to make sure the valve springs can take the higher lift and RPM.
The LS1 comes standard with 1.7 lift. and after market kits at 1.85.
