don't shave the head unless you want no end to pinging and general trouble

I am going to swap mine back to a stock head once the weather gets nicer. If you want to do any head work the best bed would be just a mild deburring/smoothing and put some stainless exhaust valves in it. A 3 or 5 angle valve job might be something to try. I am really not sure if any of that would give you much though but it would probably run smoother. And if you are going that far into the engine a crank scraper and screen windage tray would be worth adding at the same time as well as deburring the rods and bottom end.

Also I think that piston was out of a 4 cyl so the rings wont quite line up even if you could get them side by side. I will look around some and see if I can find that picture. Maybe I will get lucky
