It sounds like you have aoil pressure problem that needs fixing right now, don't run the motor any more until you get it fixed Are those Comp Cams solid roller lifters a straight body or do they have a machined band in the middle of them? If machined try pulling the distributor and oil pump drive and use a priming rod and drill motor to prime the motor, I would remove all the spark plugs to make turning the motor over easier and the plumb a mechanical oil pressure gauge where you can watch it and slowly turn the motor over by hand (get a helper if needed ) while priming it. If it gets better and then worst oil pressure while rotating the motor the lifters are probally the cause Let us know what you find please, it will help others on here later

Oil through pushrods? I had a noisy B-motor with hyd. roller and .080 hole oil through pushrods. Changed to .040 oil through and quieted the motor! I also restricted oil to the shafts.

Update: I put the oil restrictors in and it did not seem to make any difference. Thinking that it might be the oil pressure gauge, I then tried a couple of different sending units I had with no difference. Still not convinced that I left any oil galley plugs out, I then hooked up a mechanical gauge and have 70psi pressure. It turns out it was the oil pressure gauge the entire time. I honestly don't know if adding the oil restrictors improved the situation or not? I can tell you that I am not going to take them back out to find out!!! Thanks for all of the help and the suggestions on what it might have been. Got it fixed just in time to park it for winter.
