Sounds like you are using a composite gasket. Don't. It won't last with
anything projecting into the combustion chamber, and won't last if the fire
ring is cut. Either get a shim steel comp gasket or one of the solid copper
ones

deal with it. I worked up the edge of the copper and can probably shave it
back and roll it over again but it would get pretty close to the water relief.
Can I run it protruding Jack notes says it won't last but I'm only .090 not
racing all the time so...
