I don't have a magnum valve on hand.
Wen the 1st showed up and I saw what I had I didn't want to spend the money buying the valve.
1st head was a stock replace of some kind, i don't know what that was about. 145cc int.
It had no casting number, just stamping on the end. Showed up dirty with metal dust and covered in a white machine grease or dry film.
