A word of caution here -

Skimming the block and head on a 100 is only advisable as a last resort.
The water jacket interface between the head and block are cut at an angle,
this means if you skim the block too much the water holes start moving out
of alignment with the gasket and head.  Not a huge issue but if you intend
to keep your car for a lifetime, skim the block only as a last resort.
