Pulled the top end off. The head is still within BMW spec, but not perfectly flat. Has a little fallout near the front most oil passage. BMW says the head can be within .1mm transverse and .05mm longitudinally, so chocking the oil drip (common corner on the head to leak) to the combination of the VR gasket and the slight fallout. The block is perfectly flat to my surprise, but good for the MLS gasket. I have the old race car head that will go on it for now, had it shaved with a 30ra finish, well within the 50ra needed for a metal gasket. It needs new guides but will only be on temporarily so that we can do some flow research on another head to compare ported to stock on the dyno at a later date.

Will post some pics later.
