Filling wouldn't hurt but best thing would be a sonic test. I just saw an article where that 408CI twin turbo pinto that runs high 7's split a cpl cyls in same exact place. He was making a lot of power but I doubt it was +.065'' over. Even for a lower HP or NA deal I would still sonic test it. The thin block will usually show up on the hone.

You can do it but its not recommended. I have been selling a lot of take out LS3 pistons on Ebay and I know for a fact there were a few guys buying them to make budget 6.2L engines out of 6.0L truck blocks.
Like stock48 said the block should be sonic checked as the cyl walls will be getting very thin @ 4.065

I concur on the thin walls on the 6.0 blocks. My machinist sonic tested mine before the build, and it was only .060 in the thinnest area of the cylinder wall. I ended up buying a new GEN IV iron block from Chevrolet and the thinnest wall he could find was .220 !!
What a difference ...
