I think the average gain is about 5rwhp. The most I have heard is 9. You are looking mostly for valve train geometry and longevity from RR's. Once you step up lift and duration the stock rockers start to widen their wipe pattern. This puts more friction and load on the valves them selves. Which in the long run can damage or wear out your valve train.
Evans. How do you like your Spec stage 3? I am going to install one in a GTO and the owner is concerned about drivability.

The SPEC 3 clutch is great. I have BFG315/35/r17 G-FORCE on the car and can pull rubber in 4th gear and at the track I have ran the car up to 5 times in a row (back to back) with no sign of slippage anywhere. Its the only clutch to have in my opinion. Ive had Centerforce clutchs in some past rides but I wouldnt trade my SPEC for it or any other clutch Ive had in past rides or seen my friends have in their rides. It will have a little chatter when pulling out for a while until it breaks in and its not designed to slip.LOL GOOD LUCK
