Here's a thread I started on the GTD forum regarding the head gasket design and the specially placed and sized coolant passage holes in the gasket.

I am wondering if you European JX engine owners get a gasket that is different from the glof/jetta version, as the parts database suggests. And am also wondering if someone with the correct gasket could at least post a picture of the gasket and at best measure the individual holes with calipers.
