A lot depend's on what your power valve channel restricter is in your metering block, mine were .082 and I ended up jetting way down in the front, because when the PV opens the jet size and PVCR are added together to give you the fuel that the motor see's, seem's like I jetted down about 13 size's in the front when I put the PV in,,,B1KEN had a chart that showed the fuel flow of the jet's and a formula that did the same for the PVCR,I have stuck to that info and it has worked good for me,,,,as far as a vac gauge I drilled and tapped a hole and added a fitting to the spacer under my carb. 
Light travels faster than the speed of sound,,,this is why some people seem bright untill you hear them speak.

I have a port on my adapter/spacer that I hook a gauge up to although w/ big cams, a 2.5-3.5 gets the job done.

I ended up w/90`s in the ft. w/a 3.5 pv and 99`s in the rear on my hp 1050 8082-3 dommy and it was chassis dynoed and has gone faster than ever this way. I usually jet down 8-10 sizes when using a pv.

I just took my intake vacuum, divided by 2 and there was my PV number. This is what I was told to do by 2 old time guys, not sure if its true but its worked so far.
