HDES-11 Evolution Super Port Flow for Harley-Davidson

Precision Hand Crafted Port-work beats mass production by a long shot. All Ports have a Tooled Finish patented by Perry Kime to increase atomization while giving excellent flow specs. A finer finish is used in the bowl area and polish from 1/2 inch below the valve seat, up and over our “top secret” radius to the edge of the valve seat.
Join Perry in part 11 of this step-by-step journey in the FLO Headworks Machine Shop where you see the results of our custom porting.

--"Double the atomization factor"--
What is an atomization factor? How do you measure it?

Out of curiosity,
What throat to valve ratio was implemented in these heads.
Thanks.

At 3:06 mins, the sound in the background .... sounds like my primary side, when mad hot!!

I've "dimple" ported before but had no way to quantify results, just suspicion. Thanks for sharing.

Ughhhh - this looks like a HEMI-HEAD ... not a "D"-Port EVO Head ?

[@michaeljohn4044]

Is this a tri angel port?
