Might be. You have only diagnosed the problem location, not the cause.

Burned exhaust valves are normally attributed to valves not seating correctly, lean burn, weak springs, valves sticking in guides.

There are on line parts catalogs for a number of companies specializing in rebuilt tractor parts. Some of the catalogs list the original manufacturer's part number.

If you go on line, visiting the companies web site, many offer to mail hard copies of their catalog, free.
