I opened up my intake ports to 40mm to match them to the 40mm aluminum CIS injector blocks I have. Also opened up the holes in the flat manifold to 40mm and smoothed out the internal edges around them leading into the inside of the manifold best I could.
There's no flat spots or shortage of off the line and around town torque below 3000 rpm, none at all!
