Default Re: 8BA lifters noisy

Update...I pulled the heads and intake and checked valve lash by setting #1 on tdc of compression stroke and adjusting both valves then rotating crank 90 degrees and adjusting both valves of next cylinder in firing order, etc. worked great and found 8 valves with excessive clearance. Replaced the 8 valves 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 with revving.
Suspect head clearance problem or rod contact with 8rt pan. If I short out 1 cylinder at a time will that isolate a head contact problem ?
