I think what it is, is that he is hopeful that the problem will be something that  doesn't require opening the engine - or is corrective with alternative devices.  Thus there is an attempt to attribute the problem to cam overlap, need of an exhaust evac-system, low quality compression gauges etc..

I can understand that. He stated he has health (heart) issues.  I'd hate to have put an engine together only to have to tear it down shortly afterwards.  On the other hand I agree that it most likely is rings and that will require opening the engine. I see the leak down test that is supposedly coming as the final answer.  If that shows that the compression gauges were accurate then I don't think there is any question.  So, I see a finality coming shortly - one way or the other.

Update - Try running the engine longer and see if the compression comes up.  Even if not to optimal at least a notable increase.  It would support the theory of the rings not yet seated. Maybe it will take more time (though unusual).  I remember once my wife took a pregnancy test and commented that she was SO pregnant that the test stick was completely colored immediately.  I then read the instructions (isn't that a role reversal) and noted that you are not suppose to read the test for 10 minutes.  By that time we were no longer expecting.

Moly rings will seat well before the cam is broke in. That's one reason we use them. What do the other sites say is wrong with the motor? Maybe its time to get an experience engine builder to take a look. Everyone knows a really good dirt/drag racer. Find one and pay him if necessary. It may very well be your cheapest way out. And just remember that two many cooks spoil the pot.
Its better to be a has-been, than a never was.

Yes I'm looking for that cure all than having to pull motor. Yes my time is short due to needing a heart transplant. But how many of you have looked for outs. God willing I'll be here for some time but a car in pieces doesn't sell to well. If something did happened. My wife would get taken advantage by scums looking to get something for nothing. If pulling motor is so easy come get you some.

Something else that might be of interest on psi.I'm at 5400 ft in altitude.a site I was just reading say 150 psi at sea level will only be 120 at 6000 ft.what are thoughts on that.

The car does not care would be my thoughts there......... .yes the density difference would drop the number some. All this casting about should clearly show you are not going to get a one size fits all clear cut answer there. Any of the things mentioned are going to affect it. I get in the 160s on 7/1 two stroke engines all day long, would still be like 130 at that altitude.  Anything I've ever built with like 12/1 went way over 200 psi or something was wrong with it. There have been a bunch of those, we built plenty of bracket race engines of all types at our family shop. 200 psi sea level adjusted for 20% off at 1 mile up still is 160. I'm at about 500-550 foot here.

My view here would be play stupid, fix the breather issue and sell the car while still together and you around if truly looking to help the significant other.

Did another compression test as follows:
#1@160 #2@145 #3@140 #4@155 #5@145 #6@130 #7@150 #8@145.
I completed the leak down test.as expected ring problem all cylinders were at 10-15% but number 6& 8 was at 40% you could here it pushing out valve cover.don't think ring upside down just not seating.or something else.where's overhauling at when you need them.only problem with selling now no one is buying.I have it on cl now, people want to trade don't need trades.

Well, it has been a tough journey. From building this car for car shows and drags, to having the crankcase pressure issues, to finding out you need a heart transplant, to finding the rings are bad, to attempting to sell the car at an obvious lose.  That is a lot to deal with in a few short weeks!

 Everything happens for a reason. So, all I can offer is to try and see the ultimate good that can come out of this. And, hopefully there are brighter days ahead after the important things are completed.

BTW, post the CL link here (I couldn't find it) and perhaps those here can direct a buyer to you. If you going to sell a Pinto, then Pinto owners are probably the most likely source of finding you a buyer.

Luck buddy, sorry to seem to bring you down and certainly not intentional, just better to hear it like it is rather than smoke.

If no one ever clearanced valve guides/springs/retainers for lift could easily be upstairs as in cracked guide, or maybe a serious seat leak. If valve to piston not correct maybe bent valve. You got big enough cam there all of that should have been checked 100%.

All that was checked.valve guides cut, spring heights all within.010+ or-, no coil binding.pvt checked.I knew it was rings .til today's leak down i was looking upper end.now I have another question what should my timing be set at with accel dual points distributor mechanical advance no vacuum.looking for idle timing and max timing at what rpms.cam as stated 284/544.just want it to sound it's best while I'm trying to sell it
