Zero-decking is an excellent way to increase the compression. You get the full effect for every 0.001" taken off the block compared to the head since a Windsor head is only a semi-open combustion chamber. I bring every block I've got to zero. Besides, it really evens out the cylinders. Its not uncommon to see 0.007-0.008" variation from corner to corner of a stock block.
