To the bigblack, dont be driven off so fast, your 261 needs the cylinders sonic tested to see if you can over bore it that far. That is if you can even find .080 pistons, I know .030 and .060 are available for the stock 3.75 bore. Im in the middle of my 261 rebuild now. You might need six sleeves, then open your wallet for that one.
Maybe Pre68 Dave will chime in, or machinist Jerry
