Its not the valves that wear. Its the heads. I had a customer with a Ford 351clevland, in a truck. it worked hard. (full throttle for long periods). With hydraulic lifters, it kept going until the valves had pounded their way, a full 1/4 of an inch, into the head. We imported some hard seats, and it was never again a problem
