Block needs to be sonic checked to make sure, and I think most 6.0l blocks are too thin to safely go .060, I think that .040 is generally accepted as the maximum "safe" overbore. IMO, stick with the least overbore that you can (.010 or .020), makes the block stronger, allows for future rebuilds (if necessary), and there is probably no measureable power differencs between a 402 and a 408.
