I don't think the hydroboost needs a different proportioniong valve. The hydroboost doesn't change the balance between the front and rear brakes as opposed to vacuum assisted brakes. It is merely a different way of assisting the application of force to the master cylinder piston. I would just use the '73-'87 disc/drum prop valve.
