Missed on this combo?

when looking down the port from the intake side there is a turn on the floor of the port that flows down to the valve seat. that is the ss or Short Side Radius.
The best way to see the shape of the SS is looking from the intake valve, backward toward the intake surface.

Take you finger and fill the shape of you Eddy SS and then fill the shape of you new head. you will fill a bigger radius more then you will see in a pic.
But sence i'm not there....a picture will have to do.
Thanks by the way.
