Not ever colder is better, think that the sleeve must expand a little for removing all the friction in the piston. If you want that your engine last, get up to 210 - 215ºF, but in race conditions a temp between 230 & 250ºF is ok. More temp than this starts to tax the life of your engine.
Keep this temperatures as a ballpark. Haven't got two engines that perform equal at the same temp, but those figures are very aproximate to what you need to search in engine temp.
