Exactly! plus you get more squish as the piston gets nearer to the head.

More squish makes more turbulence.

More turbulence makes a more homogenized fuel mixture and helps getting all the fuel lit sooner.

Bumpy pistons get in the way of flame propagation.

So over the course of time it's not so expensive to deck the block.

There is also the piston to valve clearance to be concerned about, you gotta have room for the .900" lift cam!
