I know some 10's came stamped from the factory with K301 on them. Your best bet is to measure the bore and determine from the findings what you have. I have 2 10's in the garage right now with K301 on them. Not sure why it is like that, maybe that they can be safely bored to 12hp size without making the wall thickness to thin. Just a guess on my part.
