Does anybody know what a H72 head is exactly ? Im told its off an A14 motor but will fit on a A12 block. Is this true ? I've located one with a dual carb setup that Id like to buy but want to make sure it will fit . Thanks for the help. Evan

I think it is off an A14, but check the chambers to see if they are good ones or not.

As for an a14 head onto an a12 it is quite easy from what i understand. The oil gallery to the head doesn't line up with that from the block but this can be fixed by drilling a hole, maybe around 6mm, not too sure, in to the head to pick up the oil gallery in the block and in the head. It would only need to be like 5mm deep. I would suggest putting a head gasket in place on the head and marking the oil gallery hole in the gasket onto the head. Then simply drill the hole in the head just enough for the full diameter of the drill bit to start cutting. Then the head should bolt straight on without any dramas!
