Polishing the intake port walls leads to fuel separating from the air at idle and low air speeds, you might want to make them not so shiny now to help avoid that
I would check the lift at on all the valves at the retainers with checking springs to see how close your rocker arms are as far as their actual ratio are I've seen .130 lift differences when checking rocker arms from 4 different motors when I was blueprinting a NHRA stocker motor
