To answer Mr. Mad, dramatic, horrible or toxic....NO. Calm down.
If someone is to rebuild an engine while decking the block and installing new pistons, simply selecting the correct compression height and with proper measuring and correct gasket thickness the desired piston to head clearance can be achieved with no additional cost.
This is not to compare different piston to head clearances, this is to build an engine correctly and gain any benefits from quench (squish) that is commonly known to work.
This is what most performance engine builders do in the real world, or realsville as you call it.
