update So I figured I would update this thread with the solution to problem #3, the exhaust leak on the passenger side that the felpro's couldn't fix. The car sounds so much better now and I can drive it windows up without smelling like exhaust and gas 
I got some Earl's "pressure master" graphite foil gaskets and they fixed my leak no problem 
They are a bit pricy though but worth it when you see the high quality. We checked the header flange on a straight edge and it was flat...so in conclusion if you have terrible luck with exhaust leaks like I did; copper gaskets leaked, felpro's leaked; Earl's makes awesome header gaskets!

Final update Just to update the thread, all bugs have officially been fixed 
The 80+ psi oil pressure the gauge was reading was due to a bad oil pressure switch/sending unit. I finally replaced the thing while my car was down for unrelated issues. I guess it got bumped during engine installation
This motor has tons of oil pressure...50-70psi while driving normal and 40 psi at idle. That about right for a high volume oil pump on a newly built bottom end?

Once it's up to temp, yes it varies between 50-70 psi and idles at about 40-45psi. That too much oil pressure lol? I know it's a high volume pump and 7 qt pan.....the guy that built the shortblock made it to go 10's NA.....so it's way overkill for my uses as a street terror DD car. I dunno, this is my first "built" engine. The stock LT1 it replaced had LOW hot idle oil pressure....like 10 psi...not this one though!

Its been my experience that if the ball in the blockis not installed (the one under the rear main cap, then pressure will be VERY low. Ask me how I know.
