dial-bore gauge and some visual would answer this question! 
If your unsure, and don't have the proper tools, take it to your local machine shop.

the walls might look good, but for boost you need larger piston to wall clearances to compensate for expansion. Clearances are different between manufactures. At least hone it if your clearances are good.
