¿ªÔÆÌåÓýPruitt,
Agree on the high zinc oils for flat tappets....a must have.
However, I don't agree on the hardened valve seats. I have several vintage car engines that are doing just fine on their engines I rebuilt, and the valves are seated against the original cast iron seats. There has been no bedding, seating, erosion of any
valves into the cast iron like was claimed years ago that would happen when tetraethyl lead was removed from fuel. Every few years I check valve clearances, and clearance is staying steady, meaning nothing is happening.
I've put thousands of miles on these engines.
The milling of blocks/heads to make room for hardened seats is an unnecessary risk to install something not needed..... especially for engines that will likely only ever see a few thousand miles for generations to come. Just my opinion.

Most likely you will need to have yours rebuilt. ?It should have hardened valve seats if you did not install them last time. ?That procedure may be a problem with valve in block engines. ?Maybe someone who reb uilds flat head fords? Yes, it will be expensive.
