Here is what mortec's website says:
462624.....75-86...350/400......76cc chamber, 1.72/1.5, 1.94/1.5 or 2.02/1.6 valves I am not sure how to rank these, there are quite a few head experts on the board. I am sure they can let you know the value. Have Fun

I would pass unless they are really cheap. They are light castings and tend to crack. See my other reply.
