Van Auken had CP Pistons (949-567-9000) build custom examples based on his dimensions on this sheet of paper. He created this drawing by scribing a line with the head bolted to the block, reaching in through the bore to scribe the edge of the bore. Then he measured in from the scribed bore diameter on the head and used those measurements to create a drawing. He added dimensions to the drawing (like the combustion chamber volume, valve angle from bore centerline, etc.) and faxed that to CP for them to create the shape and size of the valve reliefs, attain the 9.9:1 compression ratio, and create a good "quench" area for the combustion to occur.
