Hi everybody.
I am about to "refurb" a cylinderhead, for another engine I am building for my 740 GLE.
The cylinderhead is a bit different from what I have seen before. The combustion chamber is normally flat, with cracks between the valves
But this one is a bit concave. Do any of you know why it is concave?
The cylinderhead is from a VW LT Van.
