my understand from the 2 years of reading these types of posts though, is that the oil pressure in the heads my NOT drop though compared to the bottom dropping.
If I understand what you are saying that if the head pressure drops low, then the main galley should be a bit higher, so, if this is true, then why have people in the past said that tappin into the head is bad? I would think that tappin into the side of the head would be like setting your clock ahead 15 minuts. NAGH MEEN?

yes, readings from the HEAD, which get plenty of oil. Originally posted by wavrdr:
On a side note, I'm running an electric gauge tapped to the driver's side head....perfect fit, and readings in the 40-50 psi at WOT.

Yes the heads do get plenty of oil, but the simple fact that there is a restrictor in the oil feed from the block TO the head, which through simple fluid dynamics, tells you the pressure is lower on the head side of the orifice.
