The 15M head with the 37/31 valves is still available here in Luxemburg under part #11041-73A00 for 1230,47 Dollar (841 EURO) without valves.
I got a used one and I guess that here is the right place to ask if someone wants one.
I would like to keep the head myself but the cost for putting it back in working condition is nearly the double of a new one, so perhaps your shops might do it for less.
So here a little story to the head why it is in this condition and some pics.
few years ago I took off a cyl. head to replace the gasket (did the gasket for nothing because I found out that it was the gasket between the carb and manifold that was bad and here coolant got sucked into comb. chamber) before immobilising the car I took a second head to the machine shop to get it checked to be shure not putting a cracked one one the engine.
When the gasket change was done I gave that head to the shop for a check so I would have an "emergency" head (that's why the surface is so clean).
But a "friend" needed a head because his was cracked and a new one was too expensive.
I gave it to him and got myself another one from the junkyard.
Some time later he gave it back to me in that condition saying that he wanted to replace the guides (why ??? they were good) some are removed some broken and one with a valve stem in it.
