I would be very grateful if anyone could identify a pair of air cooled heads. I have been told they are DS heads but i am not sure. Any help would be very much appreciated. Thanks
Hi Matt,thanks for your help with this They have two plugs each and are marked301.3.256 and what looks like ZN24.21 Chris
Well they are definitely DS Heads .. look like 1100 as suggested earlier as I only recall seeing 1100 engines with black cam covers (I could be wrong) With the oil cool mount on the horizontal head I’d guess from a hyper or monster 1100
