Before you lap the valves you need to check the valve guides FIRST.
Then recut the seats with the new guides installed, THEN lap the valves by hand.

The valve guides "seem" fine. This motor only had 30k on it. There's no play on the valves I've checked so far, all fit like a glove. All the valve seats look fine too, no pitting or anything they just need cleaned up a little
