yeah. ive seen them bored to 402ci

no you cannot bore a 351w to 402ci. Or 6.0L. A 402ci 351w achieved by only boring mean a 4.275" bore. Stock is 4". The biggest I've ever seen on an aftermarket block is 4.185. The biggest I've seen on a stock block is .060. A 6.0L bore is 4.080... possible, but not without sonic checking. Basically, there is no point. To get more displacement is not a reason to bore - bore only if neccesary(ie scored/worn cyl walls).

the only way that you can get 6L out of it is to stroke it "sweet"
