Weld the head, deck block back at it.
Just because you think it won't make it true. Horsepower is KING. To dispute this is stupid. C. Alston

Fill the groove with JB weld and hand file flat. Get the head fixed. Use something other than Felpro. Run it. When I was burning up Felpro gaskets, I called them. They told me that their perma-torque and race gaskets both hold to a max of 12:1 compression. At the time, I changed over to the orange gaskets from Dvorjak racing out of Florida. Never had a problem again, until I started cracking 915 castings.

That's a good point! I don't know the exact compression as I went from an 88cc chamber to a 72 cc when I put the -1's on it. It was blue printed at 12.9 originally. I was running 116 Sunoco as it was the same price as 114 at the Sonoma pump. I scored a basically free barrell of VP 110. It sure seemed to like the VP fuel better. I went over the block with a scotch brite wheel and it just has this little etch. I think I'll run it for the last couple races after getting the head fixed. With some better ⛽️! I don't know how aggressive you are with your Scotch-Brite wheel but ANY removal of material in this area of the deck lessens the torque applied to the gasket in this critical area. Remember that if the issue reoccurs. Just an FYI for anybody cleaning deck surfaces in general. Personally I'll choose a razor blade, solvent and a rag to clean the deck surface. If it shines like new.... you removed material. Scotch-Brite has no business around an engine anyway.
