Here's a shot of the valve adjustment pucks that just arrived. Stock pucks are 31mm, I have no idea what these fit as they were supposed to be 31mm. As I said earlier, whoever rebuilt the head ground the valves real short, still within spec but so short I need to use pucks in the 3.85 to 4.25 range of which I had only a few and none above 4.00. I'll contact the supplier next week and see what happened.
Clockwise from upper left: stock 31mm puck, new 33mm puck, stock puck on top of the new one.
Does anyone have any of these thicker ones?
