I happen to like to know what my heads flow with the intake on it. That helps a cam grinder understand actual airflow and how to tailor the cam.

Were you aware some cam grinders are even putting different intake lobes on a cam for cyls 1,2,7,8 vs 3,4,5,6 due to flow characteristics being different due to the intake manifolds runner length, shape and cross section.

By your method of selecting the intake after, none of this could be done.


I also like to see exhaust port flow with a tube the size on my initial primary before any step up in diameter in the header.
