John,
Could be, however the cylinder volumes were equal from the factory, and
unless damaged thru stupidity or slightly warped (determined with a good
straightedge), I would not recommend this procedure. On the Spitfire, the head
gasket has a raised ring built in at the cylinders. This ring sits in an area
cut into the deck of the block and acts as a seal. Taking the block down to
this level invites poor sealing in these areas, and may cause oil and coolant
leaks thru other areas of the gasket mating surface. IMHO, minimal machining,
if any, should be done to the top of the block. Now the head....well

Thanks, Chris.
The general consensus seems to be "decking" at some time past. I have heard
of this procedure and assume that it has something to do with equal
combustion chamber volumes. Does that make sense?
