Looking for data on the stock squish clearance of the XB head / piston. Also, do the head / piston squish angles match? I've not yet seen these components so I'm asking from a fairly blind perspective.

I haven't measured a stock XB, but I suspect it's about like every other stock Harley, and I've yet to measure one that was under .050 as delivered.

The XB has a bathtub chamber like the Twin Cam. So it's got a flat squish band (not angled) on each side of the chamber. They use a dome in the middle to get the compression up, but the side of the dome is not part of the squish band.
