A little late in reading & responding, but I didn't see any other responses.
1. From what I have read, hardened valve seats are fairly expensive to have
put in, given that the head has to be removed, almost completely
disassembled & then new head gasket used to reassemble. &
2. The risk of cracking the head (the older the gray iron, the more brittle)
& the difficulty in replacing them is an even bigger concern.
