Just got engine running. I ran it for a few minutes then checked compression. It was at 195psi average on all cylinders.Turns out fast68plymouth was right on lifter theory. Thanks again.
I've actually been right about a few engine related issues once or twice before
Glad it seems like it's worked out for you.
