1.920's can be had that retain the balance ports... not all that different than 2"? RV MORSE MACHINE does them if you send a set... I have them and a 2.03" that does not have the balance ports and did not see all that much difference on a 383 stroker both hit 100map... what I can tell you that helped on them is the raising of the injector towers... and shave the bodies to allow the fuel lines to be taken off and on when raised... 3 gasket height worked well, but I made alum spacers and used one gasket and sealer on the tower side... made for better throttle response on a full pedal stomp... or slight press it was more responsive when the cone hit the wall... note different injectors sizes seem to spray differently, I ended up with 90's (86.5's @ 13.5psi) much better cone pattern with the 23psi I am running.
