There's absolutely no reason to spend money on hardened valve seats. The standard story is that you'll burn an exhaust valve because there's no lead in the gas.

Well there has been unleaded gas sold in the United States for over 100 years. Amoco first came out with unleaded super premium high octane unleaded in 1923.

And nobody ever heard of exhaust valves on any cars getting burned as a result of burning amico super unleaded in all of that time.

All I ever drive are antique cars. And all of them have been getting unleaded gasoline because I was never around when leaded gas was still for sale.

Unless you're Auto crossing your vehicle and revving it at the red line all the time you're not going to burn an exhaust valve running regular unleaded in your truck.
