I use DOVE HD stands, Shelby stainless rockers (bushed) and 210lbs on the seat and 480 or so open with a solid Comp roller. The stainless rockers are good for 1,000lbs.

I didn't have as many choices as you do because of high-rise heads. If the heads were off, I would use T&D. A little more expensive but the best. Will require some machining on the heads but you you will have the best. Remember, you are building a monster motor so don't cheat the valve train.
