Replaced all of the valve springs with a set of Edelbrock 5894 springs. When I lined up all 16 of the old springs it looks like 5 of them were noticeably shorter. After the new springs were installed and adjusted, I took it out for a test drive. The good news is the motor runs a lot better, power is good, and almost all of the mystery noise is gone. The bad new is I can still here it a bit while accelerating and when I hooked up the compressor to swap out the springs the number 4 cylinder was leaking bad and would only hold about 50 psi of air. The number 6 cylinder was also leaking air and would only hold 90 psi of air. All others seem to hold 120 no problem. When running theirs no smoke comming out of the exhaust and it doesn't burn oil. Any ideas why those 2 cylinders would not hold air?
