Valve Body Question

When I bought my 66 Coronet it came with a Turbo Action Cheetah #17156 Manual Reverse Pattern valve body installed. The box that it came in says (absolutely not for street use). The engine is a well built 67 440 Super Commando. The trans is a 727 with a SB torque converter. I would like to put in something better suited for street use. Any suggestions would be greatly appreciated. Thanks
