Roller rockerarms
I have the factory type adjustable and was just wondering if maybe going with a roller type setup from Harland Sharp, Comp, or the others would be worth a significant power gain. My factory ones are new but just wondering if a roller-type setup would be worth the dough.

I agree. Roller rockers are primarily designed for engines with high lift cams and alot of spring pressure. In that kind of environment roller rockers can translate into measurable horsepower gains. In an engine that doesn't meet these standards the rollers will create gains, but they are probably not noticeable.
Typically, when a person upgrades to roller rockers they also put in end stands and solid rocker spacers, and it is easy to get into the 500+ dollar range. If you have an engine that would benefit from rollers, buy em. If you don't, then there are other areas where you can spend that money to get more HP per dollar.

I installed adjustable roller rockers with end stand supports and spacers instead of springs in my 427. I bought the set with 3/8" pushrods (ball to ball so stronger) from Precision Oil Pumps, who doesn't even advertise ... he doesn't have to. Word of mouth and his service (Doug Garifo) sells his product which I think is the best on the market. I bent a pushrod once on a 352 300 hp motor due to the springs instead of the shimmed spacers, so there are benefits to be had even is power is not the issue. The ball to cup pushrod on the stock setup is also known to break at the cup.

I run the solid spacers also. You have to be sure to get the shims right or they get pretty noisy. I pretty much have the exact same setup you have going there. I run DSCmotorsport thick walled shafts and split stands.
