I replaced all the valve seats in my 59AB.
Found washers that fit in the old seat, arc weld them in.
This shrinks them, they come out easily.
Measure the holes for size. Round, yes- but it's harder.
See if the aftermarket seats will do.
I had seats made, KO Lee, I think. Not a lot of $.
I made a driver from some cast iron plumbing fittings.
The tool uses the valve guide hole to keep the seat square as it's driven in.
