Leaky intake valves would of had the needle bouncing hard.

The needle was bouncing about an inch of vacuum both ways. Something I did forget to mention was that there was a hissing sound coming from the top end with the valve covers off after cranking stopped. I suspect it was happening while cranking, but the engine turning over was too loud to hear it, but ill see if I can hear it today, I assumed this was in part due to the valves not being all the way closed.
