Thanks Julian,
I can see where the confusion is happening - (apart from the manual!)- my cylinders are stamped as follows:
4. 5
2. 3
6. 1
Fan
Cheers

Confusion yes. Mine are stamped as Dave's. Is this method of head numbering to match the distributor cap numbering, whereas Julian's numbering is assending numerically from the fan pulley rearwards? Also Museo Motori states 1 4 3 6 5 2 as firing order. Would anyone here be able to post a schematic ht lead diagram perhaps in plan view of what works correctly . My distributor numbers match my head stampings at present. Richard
