in the spring im planning on installing headers and what i thought was a cam but tuns out to be roller rockers. the guy we bought the car from owed it to me. anyways im a little confused as to what they do or how they will increase my performace with the upgrades i already have plus the headers. any information would help.

Roller rockers decrease the friction in the valve train.They cause less valve stem deflection and thus valve guide wear.More accurate valve timing is also possible due to less pushrod flexing.Less pushrod flex equals more uniform cylinder pressures and less chance of intermittent/occasionaldetonation.

Roller rockers are an improvement over stock rockers, but you're probably not gonna notice a LOT of difference just by themselves. Now if they were high ratio roller rockers then you're doing something noticeable. Adding high ratio roller rockers will increase valve lift without changing the camshaft.

im getting the roller rockers for free soperformance/hpwise what would be the best thing to go along with them to give me the bestresults?

rockers are part of an equation involving the camshatf..so that should be noted

Make sure the valvetrain geometry is still good with the rockers. It should be, but it's much better to be safe.

Unless you want to go through the expense of a roller cam, the roller rockers sitting on screw in rocker studs with guide plates and hardened push rods are all you really need.
