Sorry, Carl I know It is 2015 and you are going to have to get up earlier to do a "gotcha" on me. NHRA is the one requiring the ring lands in the pistons to be stock width, even if they are wide.
FYI:
This is the PDF file NHRA has of the accepted pistons and their weights and dimensions.

There is no getting around the ring lands & Stocker class pistons with these part numbers being these sizes. Ring spacers can be run & the spacers can be milled so they have lateral gas ports. Creativity does exist in NHRA Stock Classes!
