What adjustable rockers to buy at a reasonable cost?

I wouldn't cheap out on rockers either. The stamp steel heavy duties are good up to 500 lift I think. Hughes engines has a good tech section on rockers. A lot of my friends have used the ductile with banana groove shafts and shaft galling is still common because you have 2 hard surfaces working on each other. That's why a lot of people have them bushed. Now your getting into just buying a good set in the first place. Just my opinion. But the longer I fool with this stuff the quicker I learn.....pay now or pay later. Usually cost more later.
