I’m interested in checking my valve train to see if it’s opening sufficiently for the engine to make rated power. I really don’t want to pull a cylinder at this time and I’ve previously read about removing the rocker box covers and measuring intake valve lift to detect a worn cam lobe. However, I cannot find the specification for the measurements anywhere.
Does anyone know what the measurements should be on an O-320, or know which source document details it?
