Thanks @StefanS of the response, in fact wanted to mount the pistons of the WR motor with higher combustion chamber. I did not know that the WR tested had not one of the two flat sides, I will look other newspapers to understand what you said, thanks again.

hello and thanks in demand: there are no breakages to the valve seats and the valves are ok. the engine died just because he was out for 20 years and you have to rebuild it. I put the link of the restoration of my URI, thanks.

Grüße an alle Ich bin die Wiederherstellung einer URI 1981 und ich in dem Motorzylinderkopf 035 103 373 AD gefunden, ist der Motor stattdessen ein KG-Code, wahrscheinlich, weil es in der Vergangenheit war gebrochen.
