decking is the process of cutting the BLOCK to optimize the combustion
chamber volume. In short, you cut the block down so the block to the
top of the piston at TDC is reduced / eliminated. There are instances in
the extreme where decking can make the pistons stand clear of the block,
but we don't want that. On a TR6, using the Kastner suggestions, you
reduce enough unswept area to gain about .3 of a compression ratio (e.g. a
head milled to 10.0:1 becomes 10.3:1 when the block is decked.
