Polishing A Stocker Intake

"Must retain the unaltered stock manifold, consistent with year and
engine horsepower claimed. Grinding, sandblasting, or any other
modification to manifold prohibited. Any film coating inside
manifold prohibited. Runners and plenum must retain OEM
appearance. Final acceptance at the discretion of the NHRA
Technical Services Department."

I'm with Chipper. I interpret the rule to mean that polishing would not be allowed.
