I ran across this in my travels/research. Maybe it will help you...hopefully it doesn't add to the confusion.  Pretty sure this may be the flow sheet from my heads I've posted here a few times. They are the normal MP aluminum street hemi heads CNC ported by MCH. Make well over 800 hp on pump gas on my 572" hemi.
