Sounds like the story with your YS 400 was the new Cams valve lift combined with the stock amount of retainer to guide clearance , factory production machining tolerances adding up to be not in your favor and in heavy throttle , added heat followed by expansion of parts with the end result of collision, with maybe some valve float thrown in the mix just for more fun, lol!
