Jeff, while your intentions are good, technically I believe you're incorrect.
To whit: the infamous (and ad nauseous) Nissan 510 camshaft debate. Factory cam no longer available, parts department supercedes a replacement that is not to the same specs as the original. There are ongoing arguments on this here, but the general consensus is that this replacement cam is illegal unless it is specifically allowed on the car's ITCS spec line.
Example 2: VW camshafts. Not specifically listed, but are allowed (but on one can seem to find the supporting documentation and it's not listed on the spec line).
One can take this line of logic to its idiot extreme and say that unless listed, even mechanically exact replacement parts are illegal if the factory part number changes (which it does constantly). However, I sincerely doubt you'll get protested on something like that.
Bottom line, the regs that apply to you are ITCS 17.1.4.C:
"Parts or assemblies which the manufacturer lists in factory service manuals or parts guides for a particular model which supersede or replace original parts or assemblies are permitted. Documentation of the superseding parts or assemblies must be supplied to the Club Racing Department and the appropriate part numbers listed on that particular model’s specification line."
Your best bet to CYA is to start negotiations with Topeka to get the superceded parts listed on your spec line.

P.S. Bill et al, can we please avoid YANAVWCD (Yet Another Nissan and Volkswagen Camshaft Debate)?
