Abstract
An improvement in a cast head for a high performance internal combustion engine of the type using wedge shaped combustion chambers where the opening of each combustion chamber includes an undulating curved edge portion extending inwardly towards a position between the two valve seats in the form of a generally V-shaped protuberance. A built up mass of cast material sloping from the protuberance towards the valve seats guides gases from the combustion chamber through the exhaust outlet primarily and, to a lesser extent, from the intake inlet into the combustion chamber. This velocity increasing mass of material adjacent the exhaust port of the combustion chamber increases the velocity of the exhaust gases through the exhaust port to improve breathing of the internal combustion engine.
