If you have questions on the plating then now would be the time. Between the pits and the tool marks being incorrect I would service them as I plan to drive my engine for a decade or better before the next service. If this is going to be a garage queen or museum piece then it might not matter as much if the plating isn't perfect in there.

$195 per jug, ~4wk turn-around time. You will need to provide specs these should be plated to; bore size, piston size and suggested ring gap would be useful to have on hand. The jugs are rather porous so some light pock marks will always be present. These guys won't be able to repair/weld casting damage but they can replate to spec. (802)-487-1000 x111 is Shawn who handles all these as they come in.
