Work with the manufacturer to have the piston made, however, the manufacturer has to submit the piston to NHRA for approval.
Also, make sure the submitted piston is the same weight or heavier than the spec. Although NHRA checks the total assembly weight during a teardown, they will reject a submitted position even if it is a few grams lighter than the spec.
