bored out c20xe

[valvercorsa]

stripped my engine for a rebuild and found that my engine has been bored out to nearly 2.1cc is this a good or bad thing?
also the head has been skimmed to max and pistons have got a few little marks on from where the valves have hit, can i make the cups in pistons abit deeper?

You can pocket the pistons yes! As for being bored out to a 2.1, good as it hould make slightly more power, but can be bad as if you need to rebore in the future there wont be much block left!!

how much more can they be pocket'd? how much can i take off?
