I boroscoped my engine today, The general order (the cylinders are in order 1,2,3,4) is...
- Straight down on Piston from spark plug
- Cylinder walls (looking for hone marks)
- Intake / Exhaust (I swapped order)
- Intake / Exhaust seats (I may have swapped order)
- Intake / Exhaust stems
They are located here...

My analysis is this (and this is my first time, I'd like a critique if you can)
- The cylinder walls all showed good honing
- The exhaust valves showed even round patterns, no edge burn
- The seats don't look smooth and clean, but I can't tell if that bad
- The valve stems all looked good, they showed excellent clean stems
- Exhaust valve 4 didn't seem to open as wide, not sure what that means.
I really appreciate any help you can provide.
