428 Cobra Jet question re Aluminum intake in STOCK

It may be a mistake, checking on classracerinfo.com I found the only restricted manifold was the -C cast iron
Intake. The intake manifolds vary depending on hp ratings and heads used.

Intake Manifolds: Casting No.
C6AE-H Aluminum
C7AE-F Aluminum
C8OE-A Cast Iron
C8OE-C Cast Iron May not be used in Stock, SS ONL

I looked at the NHRA blueprint file, note #6 is alternate intake and list the two aluminum intakes.
Where did you find the “may not be used in stock” note as I don’t see it?
