Hi i have a hpdi piston ,we were told we can used it with the 64d piston rings. Hpdi rings have like steps, 64d dont. We really would be happy for the help. This is a 200hp carburated engine 1995.

Use only the pistons and rings called out for the engine. The HPDI rings are designed to add more lubrication to the piston. The carb engine doesn't need extra lubrication. The piston is also different, and will not work in your carb engine.
