Smith, Jr, R W; Smith, M E

This patent describes a replacement type, high-performance cast cylinder head characterized by a closed-end, low profile, wedge shaped combustion chamber for each of several in-line circular pistons extending from a flat base surface into the head, each combustion chamber comprising; (a) an especially-configured opening at the base surface from which the chamber extends. The opening defined by a first peripheral portion extending approximately halfway therearound and a second peripheral portion extending about the other half of the opening; (b) a gradually tapering first surface extending into the head from the first peripheral portion of the opening, a second tapering surface extending into the head from the second peripheral portion of the opening. The second tapering surface being at a steeper angle than the first surface and the first and second tapering surfaces intersecting one another at a line in the chamber furthest removed from the opening thereby defining the wedge-shaped configuration; (c) a circular exhaust valve seat in the first tapering surface defining an exhaust outlet and having a first axis; (d) a circular intake valve seat in the first tapering surface defining an intake outlet and having a second axis; (e) a spark plug receiving bore in the second tapering surface generally between the first and second axis.
