Im my opinion you should only over bore an engine for cleaning up the
bore. There is no reason to bore an engine when you hardly gain anything,
like with my .030 over 440, I got a whopping 5 cubes... wow... and with
stock pistons I would have lost some compression... no reason to bore, if
you want cubes, stroke it, that is the only way to effectively get
cubes.... again, in my opinion...
