Valve Seat inserts

[8EL]

Does anyone have anyone with experience with valve seats inserts care to share their preferences? I have not installed any for years, I remember using Chromalloy "Valve Seat Rings" manufactured by the K.O. Lee Company.

I would expect they are out of business now. I see that Martin Wells markets a W-505 heavy duty valve seat for the little Ford engine. This number also crosses with TRW and Fedaral/Mogul, so they are available.....

What are your preferences of manufacture? the best service life I would guess to be high on the selection list. I don't mind paying a little more for the better part if it will last a long time.....
