I actually have a complete head here and just sold a 1.2mm Athena, you can pick up gaskets for £20-30 oem spec. You can even find them cheaper 4efe and fte's use the same one, I'd sell you the head but I work so much sorting it out and sending it's going to be a pig. A lot of forum member offered me cheap gaskets when I thought mine was on its way out, so try the wanted page, heads are also pretty easily come by all in all you should be able to get away with £100 area for head and gasket
