On your second question: I locate the noisy lifter by laying the stem of a mechanic's stethoscope on the lifters one at a time while it is running. Otherwise, it all sounds the same to me. The only sure cure is replacement, which requires removing the head. The secondary cure is to make up a little "hat" for the offending lifter to take up all of its travel save .007". This will make a satisfactory quietness but requires careful measurement. The third and least successful method is chemical magic from the local auto parts store.
