Cylinder head set »Knucklehead« by Cannonball
These Knucklehead style cylinder heads are precise reproductions of the stock counterparts and show all the small details like cast-in number tags and foundry markings. Thus they make for great replacements for your worn top end or to build a factory look-alike engine. They are manufactured after 1940-1947 heads with large intake ports. The pre-installed, but unmachined valve seats are sized for stock intake and exhaust valves and hardened for the use of today’s unleaded fuels.
Tech Tipp
Cannonball cylinder heads come unpainted and for good reason. It is difficult to protect your new paint, when machining valve seats, installing guides and tins etc., so we recommend to paint just the area around the guide holes and then press in guides with tins, machine seats and install valves. Once this is finished you cover the tins and completely paint the heads. This will guarantee a nice and unmarred paint job.
