Heads have chamfer on the sealing surfaces? I don't think they should, at least not any of the CE ring heads. The 3.2s did as part of not having CE rings, but you couldn't put those heads on your case unless it was an SC case or later, and it can't be that or the Birals wouldn't fit.

I don't know enough abut the 2.0 heads, which have an actual gasket between head and cylinder - but would you have those if they even have a chamfer? I can't imagine the crush rings not making contact. Obviously you didn't see signs of distress in this area on disassembly - no burn marks or carbon deposits in odd places.

Odd, but all's well that ends well.
