1Faastc10 is absoloutley right. I was only making the compression comment earlier in the post, because it's a common misconception that an overbore makes no difference anywheres. Stick with the smallest overbore you can get away with. Not only will you be able to rebuild it again, it will most likely give you less trouble. .060 is most likely OK, but for God's sake, spend the extra few dollars and get it sonic checked. A few dollars spent on that test may save you alot of grief later. Good luck!
