The 647 piston's combustion bowls differ in configuration from the 612 and the 647's smaller valve diameters may mean there are slightly smaller valve relief pockets on the 647's piston crowns (I don't recall and I have yet to unpack all my pistons to compare for you) but otherwise there should be no issue.

Be sure to use the 647 flexplate (flywheel).
