I have an old but rebuildable head that I believe is from a XK120SE but not sure. The head/engine number is F3997-8, casting number C6733 and it has 1 1/2" intake and 1 3/4" exhaust valves. Is this from a high performance XK120 engine?
Any idea of its value? It has the cams (but no cam bearing caps), missing two exhaust valves and it has the valve covers.
Thanks for your help.
