sorry never answered your question - .040 is to close i dont care what the MC Donald's crew sayes ( BTW they all have 750 HP cars on pump gas and only street drive them ) it is in the rock of the piston how much is not enough not trying to tell you how or what but you will waffle an intake valves just enough to loose 30 or more HP and no consistency -- jz
