Title: Head Shaving
Post by: flyingbrickperformance on November 22, 2011, 07:06:39 AM
Anyone know the specs on the M42 head and how much it can be shaved without creating any problems?  Thought I had them in a post here, but can't find them.

Std = 140mm
Max = 139.55mm

If you machine 0.3mm there is an alternate 0.3mm thicker BMW head gasket part number.
