Default pushrod mastercylinder gap

so have problem....in every explaination they say the pushrod from the booster to the master cylinder should have no preload and at least a gap of 0.020...
so have a new right stuff ac delco moraine booster mastercylinder combo for my 68 disc brake firebird ..i also bought the expensive bear brake measuring tool to check the gap...the combo has a massive preload on the combo you even feel it by putting the master cylinder on the booster the booster rod is not adjustable..so i turned off a good amount of master cylinderadapter to get the right gap.... but now to pedal is so near to floor tooks a lot of travel to activate the brakes....friend has the same problem...he installed it with preload so what is going on here...????? Check on my other car also preload !!!!!
Seems that all BOOSTER COMBOS HAVE A LOT OF PRELOAD:... but it shouldnt be there...??????
