I found a few of the lock nuts loose on the adjustable tappets,I doubt if they were properly tightened down.I found that I was not able to get a wrench on the machined part of the tappet because it did not come far enough out of the lifter bore,I removed the head and valve springs to be able to lift the tappets higher out of the bore to be able to get a wrench on the flattened part of the tappet.I was then able to set the clearance.What is normally done when using adjustable tappets,are the lifter bores cut down?
