Cub 108 valves
 

Howdy folks I just got a cub 108 and it’s got a burnt exhaust valve and I’m going to replace both the exhaust and intake valves in it is there any place that would sell them online or a physical brick and mortar store

I would start with Cub Cadet Specialties for the valves.
Link is at the top of the home page. Congrats on the 108

I've always found the easiest and quickest way to locate a part is just Google the part number.
In your case, KH235826 and KH235008.
(assuming you have the original K241)

You may want to consider replacing the valve guides as well as resurfacing the head while you have it torn down that far.
Good luck with your repairs.
