Absolutely true.

I just poured a set of 441 and 041 sbc heads that were junk yard pull offs from years ago, never been race prepped in any fashion.

The exhaust ports on both sets were within 1 CC of the superstock spec. A change to aftermarket valves will put them over the limit. A valve job as per the 2009 rules will also create an issue.
