Static pressure is not operating pressure. Including pipe and fittings and valves and backflow preventer, you could lose 20 psi, and that's before you turn on a zone.

Now I'm really confused, everything I've read says around 60 psi is ideal???

I would think twice about using those heads - 78 psi static is on the weak side, all told, unless this is a curbside meter feeding a small lawn.

pressure regulator

My static pressure is 78 psi and Im going to be using Rainbird 5004's with the internal pressure regulator. Do I need to use a pressure regulator for the entire system? And if a regulator is used does that have an effect on the GPM?
