Another convert! Welcome!
I'm glad you got that chance so you can see and attest to the fact that fudging with the airbox is just not good enough to get all you can out of these motors.
With you Staintunes, the 160s will probably be just right. Leave your pilots unless you see issues with the bottom end. I did not and still have the stock 42s.
You are going to be very happy soon!
