Well it looks like I'll have a modified head after all, eBay comes through again.

Not exactly perfect, not exactly what I would have wanted, but then again not exactly $1000+ either! I'll clean up the combustion chamber in #1, cc it, and touch up the other to match (if needed). I'm a little concerned that it may have been shaved a bit too much for regular street use (3.27 inches thick vs B20E 3.34, B20B 3.39). I'll have to cc it to see how large those chambers still are - they look to have been reshaped at least a little. Perhaps I'll regain some CC's by extending the chamber on the long ends of the ellipse to match the 92mm bore. If the compression ratio still looks too high after doing that I'll just get a thick copper head gasket and hope for the best.
