Bob, the best thing to do is ask Strange what master cylinder you need. The proportioning valve is probably going to need to be an adjustable from an aftermarket source like Wilwood. If the master cylinder is ABOVE the calipers and the wheel cylinders, residual valves aren't usually required. If you're buying or have bought brake parts from a company, then let them tell you what to use. Part of what you're paying for is their help and expertise on getting it all right and working safely. The brake system is no place for guess work or Rube Goldberg engineering.
