I made up a tool like KustomKartKids for turning/milling a flathead Briggs cylinder head in the lathe, and I am wondering: how much material are you taking off when you are milling your heads? I don't mean for a racing application, just a general modded 5hp Briggs.
I ran this head for a trial run and I ended up taking .045" off.
