As promised, I am reporting here the results, of my installation of "one man" speed bleeders.
I chose Speed Bleeders over the other two brands of these type brake bleeder valves, because I found the right sizes from this company. If you are not familiar with these gadgets, they look like a normal bleeder screw, but they have a built in ball bearing type valve that only allows fluid and air out - will not let it back in. Thus, one person can pump the brakes, and when finished, can go under the car and close the valve, without allowing any air in the system.
I installed them without a hitch, and they worked beautiful. I now have the hard pedal that I was aiming for. I also adjusted my rear brakes (Thank you mjamgb {Mike!} for the good advise).
I am sure I could have done just as well with the stock bleeders and someone's help. I previously did this but had problems (I suspect that crud in the system was forcing me to unscrew the bleeder too far). I think having the brand new bleeder, with the sealant on the threads made the difference for me.

Anyway anyone interested in buying these bleeders (or standard bleeders as well) the sizes, at least for my single circuit Girling (front discs) are: front 3/8" x 24, length 1 9/16" ; rear 3/8" x 24, length 1 5/16". Essential tool - 1/4" drive deep socket 7/16" for original bleeder, 3/8" for speed bleeders.
