I just got back from a tech session at AutoSport in Seattle.   We saw a
Lotus Twincam shortblock assembled.  I asked about decking the block
and he uses a surface grinder.  He's taking the surface down a thousandth
per pass until the wheel grinds the entire surface.  As part of the build he
then checks the piston to deck clearance.
