I was thinking that too, but some of the internal corners look to sharp. Almost like wire edm, but the part looks too "clean" to be out of an edm.

Sbdtasos - you can make your valves seal directly in the head, and still have a durable engine. This is according to Schillings himself in his book Boxer, Reihen und v-motoren als modell. In it he states that he has over 25 years of running on one of his engines, with no bronze valve seats or anything. Simply seating in the aluminium like yours. I translated this whole book into English, which was... loads of fun.:rolleyes: But the info in it is very useful indeed.
Very, very nice engine by the way.
