Exclamation Whats yalls average oil pressure

I just put my heads on the car and i am in the process of getting it tuned, i now have it to where it will stay running and possably drivable i havent tried yet cause im having to bleed the air from the coolant system. Turns out thats a slow process with the TB bypass mod done.

Either way my question is that now i have the heads on it seems to be having low oil pressure to me anyway, i cant really remember but i thought before it was higher. It is running at idle right on the line between 0 and 40 which i am taking as 20, is this normal cause i dont think so. When i rev it even slightly it kicks up just fine.

See i was thinking that it is running or at least showing low, i dont want to risk driving it like that but Nimitz87 posted that he broke his sending unit when taking off his intake could i have done this?

Also i dont think it matters with oil pressure but i have my PCV system obliterated right now with a few vacuum lines(not sure if they actually are) uncapped. I left the lines on the back of the intake uncapped not thinking about it and could this be causing a problem?

I have a stock engine, nothing changed except to a LS6 oil pump, no mods to the pumps (porting or pressure releif spring)..

Cold start up = 70+ (needle is off the gauge)
Hot idle = 55+
Hot and While on the Throttle = 60-65

Looks like mine is a little low, too...

Lingenfelter "GM High Flow" Oil pump...

55-60 Cold Idle
25-30 Hot Idle
~40 during normal cruising

Now I'm a little worried.

When i actually looked to try and see my pressure it was after the car had warmed up so my number is from hot idle.

Hot idle is just about 45 for me. Bolt on LS1 with stock pump.
