Alloy Seat
why is that ring insert is preferable than valve seat reface where servicing valve seat of Aluminum Alloy?
Wish you had included the year make and model of the motor.
We are all forced to use pretty much no-lead fuel which has no natural lubricant (lead) in it. Lead use to lubricate and protect early type valve seats. If it was noticed your valve seats were pitted or damaged beyond repair complete replacement was likely necessary to get a good valve seal. Leaking exhaust seats will erode and damage the valve very quickly.
