Dont suppose anyone has any info on this head? I cant find any stamping on it, but it currently has paint over everything. Its an old a series 12G940 casting.
It has round combustion chambers and the ports are different shapes, it also has double valve springs, valves are 29mm and 35mm
Any help would be great.
