Default Looking for some "Brake" guru"s

Ok, couple questions here for you guys...........trying to make a long story short........got new rotors & calipers, bleeded the brakes good, no issues......

Have a very hard pedal..........thought maybe the booster might be bad or the check valve, did the pump a few times and start the motor..........on the very first pump the pedal only went down maybe a inch, second pump about a half inch, 3 pump barely moved, started car and the pedal maybe moved a half inch.

When car was off, i pulled the check valve out, got a hiss sound for a second..........also when running the motor i pulled the check valve out, ran a hair rougher, the idle speed when up.

When hooking up a vacuum gage at about 800 ish rpm, i get between 12-13, if i move the idle screw up some to 900 ish, i get about 13-14...........this is never steady, seems to jump around some.........if i give it some gas it will stay at about 18 or so and pretty much steady.

The cam is an Old Faithful in a 463

The car does stop, nothing to brag about though, the brakes will not lock up.

So im looking for some advice on what to check or do next
