Have you lowered the float height from stock?
That is almost my exact jetting, except I am back to a 42 pilot for winter and I am on clip position #2 with a 172 main. No knocking and clean crisp jetting all the way through the rev range mostly around sea level.
What is your squish set at and did they lower the compression? My stock head had way too much compression and no matter what I did with the jetting it knocked when hot.
