Do your Comp Pro-Magnums have bushings installed? If you melted the Crane Gold (aluminum) rockers, I would be worried that the stainless steel will gull to the rocker shaft?
You might want to look at modifications to get more oil to the top end (rockers, pushrods, and springs) when running the Silver State Classic.
Do you need a new cam? The cam you have seems to be designed for endurance and sustained high RPM.
For the drag racing, a more agressive cam profile and timing would add power, but be harder on the valve train.
A valve cover oil spray bar for the springs and rockers might be a good idea?
