got me stumped on the electrics bit ... i'll check a couple things and get back on that one ...

to get the head to work you need to drill a new oil supply from the face of the head thru into the existing one ... the "old" block oil feed doesn't line up with "new" head feed. they are only slightly out and drilling thru at about 45deg from the face of the head into the existing oil feed in the head will solve it. if you have the A12 head gasket and the A14 head you should be able to pick up the difference pretty easy.

does the A14 head you have not have valves in it ?? the ones in it shoull be right if you are getting the head o/hauled just get the valves that are in it reseated.
