Exhaust ports as requested. Now this valve is the only one that came out smoothly but the other exhaust valves “exhaust valves only” will not come out because of burrs where the keepers sit. I did see a little bit of scratching in this guide but I will not pull other exhaust valves for fear of damaging the guides. I believe this one may have gotten scratched when I removed the valve but it came out smoothly so I am not sure.
