NHRA has always been careful about insuring that the factories did not alter or change components after they were initially listed as "permitted" for the S/S class. 1961 was a strange year for S/S, for a couple of reasons. First, they permitted cars to compete in S/S even if they did not originally have the legal engine for S/S. For instance, although the Chevy 409 engine was legal in '61, it did not need to be a factory produced vehicle. In effect, if you had a '61 Chevy with a 6-cylinder engine or a 283 or 348 engine, you could purchase a 409 engine from your dealer and install it in the car yourself or have it installed by the dealer. By 1962, if I remember correctly, it clearly stated that the "legal" engine had to be "factory installed". And NHRA did not know what to do about the parts that came out during the year, that had not been available at the beginning of the year. In the 409 case, Chevy offered a different cam, heads and intake manifold prior to the NHRA Nationals in 1961. Had that been done prior to the Winternationals, it would not have been an issue, but it was offered in mid year, as "optional parts", and not "available as factory installed". Pontiac, Ford, and Dodge / Plymouth followed suit with mid year non-factory installed optional parts. NHRA created the "Optional S/S class", for that one event only, and it was never done again. I seemed to recall a similar problem at the '62 NHRA Nationals, with the Chevy guys running "optional" engine equipment, but it's a little hazy now as to how that got handled. Maybe they ran in F/X, I can't remember. An interesting situation happened at the NHRA Winternationals in 1963. Several Chevy racers arrived with Z-11 cars, Pontiac racers with the Swiss Cheese Panchos, Ford guys with plastic hoods, etc., etc. All Factory backed cars, but those components had never been presented to NHRA for classification. These racers expected to run in the S/S class, but NHRA said no. NHRA created the "Limited Production class" (L/P) for that one event only, and it was never done again. As it turned out, neither Chevy or Pontiac had produced enough vehicles to even qualify as "stock", and these cars were eventually classified as "Factory Experimental" at later NHRA events. Both Chevy and Pontiac built the full size cars to run in S/S, not in F/X (Pontiac already had the 421 Tempest for F/X), plus the anti-racing ban hit the GM Divisions. Ford went ahead and did build enough '63's with light weight hoods and doors to qualify for S/S, but that did not happen in time prior to the Winternats. I never did follow up on the Mopar guys and their issues. NHRA cleaned up their S/S rules after '63, added clarifications where needed, and created good connections with the factories, and the issues of '61, '62 and '63 did not come up again, as far as I know...
