I have a Crane AFPR and the instructions do not say which way to turn the adjustment screw to adjust it. clockwise to increase FP???

All regulators I've ever adjusted are CW to increase pressure...but, you are going to be monitoring the change with a pressure guage, right?

Yes, I have a gauge on the schrader valve on the passenger fuel rail.

Heres what might be a dumb question, but considering I have no prior experience modding an EFI car before.....at what point do I start measuring.
I am not starting the car, just trying to set initial FP with the key on only, so i can start the car after doing a head gasket job.

DO I start measuring FP when I turn the key on, or wait a few seconds for it to stabalize??
