Thanks for the help, guys. I really appreciate it. I took off the head last night and here's what I saw. Not as bad as I originally thought. The exhaust and inlet valves are still seating perfectly on their seats. No wiggling or movement on the valves either. No cracks. They just have a lot of carbon build up, which I assume is normal. Any advice after seeing this? I don't think it would hurt to have fresh valves... Exhaust valve closed: Exhaust valve open. Hard to see the seat due to carbon build up on the outskirt. The actual seat where the valve rests itself is clean as a whistle.
