It is 0.021" deep, so my guess is too deep to grind out, but that is just a guess.

As I mentioned I've never had to contend with grinding a valve seat with that kind of damage, but I suspect your guess is correct. The biggest expense in having valve seat inserts installed is going to be labor for removing/reinstalling the engine block unless you're fortunate in finding a local engine rebuilder who has the tool to cut the block for the insert with the engine in the car.

Sorry to hear about your problem and your advice about using something to shield the block while you pound on the guides is worthy of emphasis.
