roller rockers?

Honestly, not really - most people do it for a more sturdy rocker (some stock rockers can spill needle bearings), but stockers are more than enough for most setups.
Crane has some quick lift rocker arms that may offer some small gains, but last time I checked, they were really expensive.

Your stock rockers are not roller rockers! They are just rocker arms. The only way you can get more power by changing rocker arms is by changing the ratio. Go from the stock 1.7 ratio to say a 1.8 ratio. That will give you a little more lift with the stock cam. If you are going to be putting in a cam then don't waste your money on new rockers unless you are changing them with the cam.

But the stock rockers are stamped metal with a plain flat tip, not roller rockers. Am I correct? This is a picture of a rocker arm verses a roller rocker arm. Sorry for the confusion.

No problem at all. The LS engine rocker arms have roller bearings where they are mounted to the cylinder head- the pivot point. They are just plain tipped though - where they touch the valve. Aftermarket rockers will have a roller bearing at the mounting point and at the tip that touches the valve.
