Block mods?

Ok so I keep mulling over results in my head, so I need clarity although maybe a dumb question Lol.

What would the result of a block being skimmed by a couple of mm. This would bring it flush with the pistons I have.
Technically I was thinking it would make the throw shorter allowing slightly harder revving?
 
The raised compression sounds good.
If the pistons are shorter in the block then skim the block so the pistons are level then they should be able to run without hitting surely?
 
the stock pistons are flush tho eh paul, but if you mean corsa pistons yeh
i machined these 1.0 pistons so that they would clear the quench steps when used with a CGA3 crank :)

you get a bit less chain slack by skimming the block instead of the head eh (because you are skimming the full 71mm dia)
