I am finding out that finding pistons for the 5.9 Magnum I am building is more difficult than I intially thought. I talked to a tech. rep. at KB today who told me since I am truing up the deck and the heads (~0.020" total) this would cause me problems with the piston being above the deck and not enough quench area. He said their pistons are designed to be zero deck and that I'd end up spending a bunch of money on custom head gaskets.
Please help me out here I know this can't be this difficult.
