Yep, the only way anybody is going to hit 580 WHP on the stock block is to run E85 or at least race gas.... both of which necessitate extra fuel capacity which is pretty massive at that kind of power level (700 bhp or so).
Though, the VHR doesn't like to make massive amounts of torque, so you may be able to get away with a serious amount of top-end power before you bust a piston. Torque kills rods, power kills pistons - generally speaking.
580 crank HP is probably closer to the actual limit.
