You can also use the drum/drum blocks as they are just passthrough as well. You'd want an adjustable prop valve to fine tune your brake bias, not just if the rears lock up first -- I think 70%/30% is the rough target I've seen quoted most often for brake bias, and this has a lot to do with the difference in brakes between the front and rear (pads, calipers, rotors).
