advertised numbers only mean jack if you are fixturing and testing the cylinder head in the same exact manner that was used to obtain the advertised data... and honestly, you'd want to test with a fixture very similar in dimension to the engine you are putting it on in order to achieve any meaningful data for your application... unfortunately tou rarely see the "important" information passed on with advertised airflow data... other than the depression it was run at... so just take it all with a grain of salt... gotta love fluid dynamics and creative marketing
