2004 Acura MDX Question: Can mdx be driven with tight exhaust valves?

It is not advisable to drive with valves that are too tight. - DaveJHM
Who said they're not adjusted correctly? As they heat up while your running the valvetrain expands. If the clearances too tight now your valves won't fully seat and you'll burn them needing an expensive valve job costing over $2,400.00. My Dublin shop could perform the valve adjustment for $360.00 plus the gaskets. - Hal...
