I mark the bore diameter on the head then I draw a line on the deck surface at a right angle to the intake gasket surface right between the valves up to the gasket area. I then cut a slot 0.060" wide a 0.060" deep with a ball end mill being careful not to damage the head gasket area. I widen and deepen the groove into the combustion chamber cavity to 0.125" with a hand held hacksaw blade and a triangle file.
