Hey Trent, I just installed a set of Comp Cams Ultra Pro Magnums,#1621-16, they're a moly steel, were quieter going down the road than my aluminum set, my spring pressure around 220 on the seat and 430 open if I remeember right, .600 lift solid roller, no problems with them on Drag Weekend or mdriving around here before hand.
Another good option and I ran those for years w/a solid flat tappet cam before steppin up to a solid roller myself BUT, was told by Comp. those would be marginal at my 580+ open pressures I now run.......
