Permitted per NHRA Specifications available from NHRA Technical Services
Department headquarters. Stock factory OEM Components (unless otherwise
specified) must be retained and remain unaltered (i.e., cylinder heads,
connecting rods, pushrods, crankshaft, etc.).

Clear as mud especially when aftermarket cylinder heads are allowed.

I guess I don't how that wording changes anything with the way the rules were written before... It already spells out what can be done and what can't be done as far as "alterations" so that would fall into "unless otherwise specified" meaning that all the heads that passes last year will pass this year just the same..
