340 issue after camshaft change
I never have used the MP valve adjustment chart. Never have used the EOIC or ABC, XYZ, PDQ or LQBTQA+ method or whatever the hell else there is. I get ONE camshaft lifter at a time on the base circle of the lobe and adjust that valve and move on to the next. Always done it that way and it's always worked well "FOR ME". That means turning the engine to close the valve you're fixing to adjust and turn it "a little" more to assure that lifter is on the base circle of that lobe. Anything else is just too complicated for my simple mind. You have the valve covers off. You can shine a light into the intake valley through the heads and SEE the camshaft lobes and lifters and make SURE they're on the base circle. Simplest way ever to do it, IMO.
