I almost always have any blocked decked to ensure that it's square and has a flat surface. That's pretty much a given. But I'm trying to avoid spending the extra money DSS charges for a custom compression height every time I buy pistons from them. The 10.210 assumed deck height they use will pretty much always put the pistons in the hole .020 or more on an uncut or slightly cleaned up block.
