I don’t know much about Knuckelheads so please look at the pictures for information. I think this is a rear head for a 1940-47 motor. I also believe it is a large port. I see others make a note to mention the condition of the exhaust port. This EXHAUST PORT is NOT cracked. Don’t do Krack. There don’t seem to be any combustion chamber damage. There seems to be one small fin broken near the spark plug hole. It is dirty and rusty. One valve guide has been removed and one remains. The intake manifold nut is still attached. I tried to turn it by hand but it didn’t move. There are lower tins on both intake and exhaust. The valve seats look pretty good. Please study the pictures for more info. There are a few places where it appears to be some welding done in the past. The work looks good but could be cleaned up even more. This head needs some work but not the difficult crack repair that is seen on others. There are no additional parts. The numbers stamped on the head are 119-352 and the date code is D 29-1 If you have questions I will do my best to answer them. 1940 1941 1942 1943 1944 1945 1946 1947 40 41 42 43 44 45 46 47 F FL Knuckelhead OEM.
