Just remember everything you take out of the bowl lowers the compression. If BBC you should look un-shrouding the valves.

Just a dremel and sanding drums. You can buy them off amazon in an assorted pack for cheap. I took out 10cc worth of material that dropped compression nearly a full point. I was getting new pistons with a higher dome anyways but blending the chambers can have a big effect on compression. I’d say that I have at least a couple hours into each chamber times 8 and there’s nearly a full work week into just sanding. At the end it would’ve been easier to find some cnc heads.
