Ken Gillanders chastised me thoroughly for doing this to the block
that's currently in my car; unfortunately, the top surface was so
badly scored that I had no real choice. If you can avoid decking
the block, don't.

The problem is that with the wet liner block, you'll have to measure
the "protrusion" of each liner, then have a machinist chuck them in a
lathe and remove a few thousands to get the required protrusion. Of
course, if whoever decks the block doesn't get it exactly square, you'll
have to mark the liners for both position (1,2,3 or 4) and orientation
within the block, etc. Also, if you're running a high compression
motor, you may run into valve to piston interference or your rods
may be too long, you'll have to compensate with shorter pushrods, etc.
So, its best not to skim it unless absolutely necessary.
