Thats is exactly where the exhaust valves for cylinders 4 and 8 slightly touched.
I think I will use copper gaskets that are thicker than the graphite. Graphites run about .0050 thick after crush and copper are about .0062 after crush.
Looking for another set of Mercury heads now that have not been shaved as much as the ones I used. Thanks for the photo.
