Default New Stock Replacement Head Buyer Beware

Just looked at the Dart 10021070 heads today for my combo and the runner volumes are so LARGE that there is no way that you can make them right, sucks to waste that money when they are advertised at Dart as 165/65 runners( my mistake)

Could it be they just "look too large" as numerous sites including Dart,Summit and Jegs list them as 165/65 ? They suggest a Fel Pro 1204 or OEM intake gasket for use with these.

So adjusting or "adding" material is illegal in stock and with NHRA have IR volumes on both the stock and replacement head wouldn't you fail tech either way? Not running the stock IR volumes in the replacement head? I see NHRA just allowing the replacement IR volumes to be allowed from here on out.
