Ok I'm feeling a bit better. Valve leak. I did a poor man's leak down test ( pressure directly to cylinder with schrader valve removed from my compression tester line) and, sure enough, both intake and exhaust are leaking big time. Pulled a valve cover and removed the rocker pressure on the tested cylinder and the air rush almost ceased. So.... Got to go back and check the lash settings on this engine. Must be that. Have Edelbrock Performer heads with the small valves and stock push rods and lifters. I'm assuming it's not the push rod length.
I do thank you all for saying something other than cylinder wash. Regards, Jon
