I was at the repair tent at the National MAFCA meet in Reno a year or so ago and a chap there had an engine done by them. It had stripped the second timing gear in about 400 miles. A new one was fitted in the hope that he could get at least nearly home again to (I think) So Cal.
IMO, fitting hardened seats in a Model A engine should ONLY be done as a last resort. I've never done it and can't see that I ever will.
The OP is doing the right thing seeking advice before parting with his hard earned.
If a hard seat comes out, it's the machinist fault, not the seats.

We are shooting a 100%, in 55 years.
