07 EC250 Cylinder head engine mount

[WTEC]

Hey everyone, long time reader, first time poster.
Has anybody else had issues with the engine mount on the cylinder head? I had two sets of aluminum mounts break, then I made some stainless steel ones and the mount on the head cracked down the middle. When I get a new head I'll have a good look for misalignment, etc., but I find it hard to believe that the mounts would bolt up with a significant misalignment, it's a pretty tight fit in there.
