"Stuff happens". We all make mistakes.
Just an FYI - the intakes do not recess like the exh valves do. I've never, in 30+ years (including my years as an ASE Master tech), ever had to replace an intake seat. I have heard of damaged heads needing them - so it can and is done. But usually it's when you're going with the same size valve, and the damage to the existing seat area is so bad you would have to sink it and really mess things up... Going with the next size up intake valve usually solves the problem, and increases flow potential of the valve job as a whole. So just for next time - intakes will not typically need replacement seats unless there's significant damage and you need to retain the existing intake valve size.
