thanks, but I can't really go any further on my engine without spending serious coin, something I can't really justify (besides, larger valves would help top-end only, an area I don't visit too often, my time being spent mostly in the mids, where I want explosive response and acceleration). Was just curious about the stock diameters...

No worries. I do have a set of stock valves on the work bench. I can measure them the next time I'm out there.
Won't be exact but I can get you a close number
