Here is what they flowed on my bench with a 50º intake and exhaust seat.

Here is what they flowed with an hour of work. Sized the bowl, moved the wall, pushed the PR area and finished the chamber.

Do you have any measurements to share on these heads? CC chamber and runner,port lengths and CSA?Any special manifold requirements?
Looking good by the way!

I haven't cc'd the chamber or measured the length yet. The runner is right at 2.95in² min and 300cc's. Takes a 15º manifold.

I'm not done and want another 15 or so cfm.

This might be the port I have digitized. I took some high flow for more mid..

How does the velocity look compared to the SB2.2??

The SB2 is a little different animal. This profile is unreal to me, should make tons of flat killer power!

Chad not sure if you are willing to spend the time but I and maybe others would be interested to hear your thoughts on why different heads are "different animals". In the past you have said that 23 degree heads are velocity limited so obviously as the angle goes down things change. As an end user things like "flow curves" and "csa" are the only things that we have to go off but it would appear that there's much more involved depending on the casting than these parameters.

Appreciate any feedback and always looking to learn. Thanks.

Basically, the taller the port, the better the mach index. So you can run the port faster via airspeed. The 23º being a low port has a bad "line of sight" for a lack of better words. Therefore you cannot run the speed as fast. That and the pushrod is will always be the killer on a 23º. This is why some, including myself, are so hell bent on making it match the amount of air it's moving. Some 23º heads move a ton of air but will never see it because you simply don't have enough area. Now a higher port can have the same area but due to the port shape, can run a faster airspeed, and still make power. Velocity is VE. The higher the VE, the faster the airspeed usually is.
