Hi everyone.

I'm rebuilding an R56 N14 motor for a 2009 Mini Cooper S and I bought a new head from eBay where the guy said he did a resurfacing. But he did not specify how much material was removed and now that I've bought it, doesn't seem to want to respond to my question.

In any case, I'm trying to decided if I need to order a thicker head gasket than the standard .90mm one. They make a 1.2mm one, which is .3mm larger. I had someone tell me that a typical resurfacing job can take as much as .25mm of material, so that would be about right.

Thoughts? Do I need to worry about it or should I take the extra compression?

I have the old head still, maybe I can measure the thickness and try to calculate the delta between the old and the new replacement somehow?

Thanks

Jason
