Years ago I had a set of .060 over oem pistons turned undersized so they would check legal for a NHRA stocker. It was done somewhere in Detroit, but the engine builder never revealed his source. Whoever did the job cam ground them to the same specs as TRW pistons. Going fast in a NHRA stocker was never cheap.
