Ryan, G-day mate!
My suggestion is
38mm ports
Bottom of throttle bodies opened up to match the port. Right now 38/36mm. you want 38/38mm
Open your stacks up to 38mm bottom 46mm at the top. It may be in your best interest to sell the S stacks and bore out some T stacks due to the value of the S stuff.
You will keep some important mid-range torque to get out of the corners and get a bit more for the straights.
If you decide to go bigger, you will need bigger butterflies in your throttle bodies.
the max you can take out of the plastic stacks are about 40mm on the bottom and 46mm on the top. Maybe 1/2 a mm more but you are getting very thin!!
Bobby,Excellent post my friend!
