Next years project but other than using a stethoscope how can I isolate the cylinder/cylinders ? Don’t think pulling the spark plug wires one by one will work. Comments

Update...I pulled the heads and intake and checked the valve lash using tdc compression stroke #1 adjusting both valve then rotating crank 90 degrees then next cylinder in firing order etc. Found 8 valves with excessive lash and replaced with NORS TRW valves and ground to fit. Started it up and valve noise is gone but have a knock at idle that seems to disappear when I rev.
Have not checked anything yet but suspect head clearance problem or rod hitting 8RT oil pan.
Will shorting out cylinders help isolate head clearance problem ?
