Billet 16 HP Aluminum Head Blank

This 1.5" thick 6061 aluminum cylinder head blank allows for the use of high lift cams and long reach spark plugs. We have drilled for the stock 10 bolt head pattern, but the combustion chamber is left completely unfinished. This alloy can be welded. It is thick enough for cooling fins to be machined if desired. The same blank is also available in the 9 head bolt pattern.

Engine application: K241, K301, K321, K341
