How worn do rockers-arms have to be before they need replacing? 8 of mine have a perfect indentation worn in from the end of the valve shaft, but 4 of these are much worse than the others. How deep a recession is still usable? My worst has about a 0.030" of wear than one that looks evenly worn. And speaking of which, I seem to have a variety of rockers-arms... the numbers on my rocker-arms range from 1192936-3B to 1192935-7B. Is there a rhyme or reason to these numbers? What is the key? Thanks, BTW... Happy New year! :3gears:
