Adj. P Valve Installation?

I have re-blead the rears with the adj. valve wide open and pedal still has to be pumped-up. I'll re-do front on Sat. and close the adj. valve to see what happens?
PS. Keith at MoparMagic informs me to leave out the Adj. P-Valve unless it is absolutly needed. If the rear with drums (fronts with Disc's) if the tires squel without lock up and stops straight things are ok, stay with stock brass unit. The adding of the Adj. P-Valve may make things worse or only equally as good as Brass unit if it is working fine on it's own. Going one size larger on the rear brake cyl. or changing to disc's is another option?
