If you are planning on doing more then I'd skip 42lbs and go with 60's.

In a scan I ran with my 3.2 setup I saw about 130% duty cycle on my 04. However I am just now seeing a little bit of lean out on my wide band at the top of 2nd gear just before the shift. I don't trust the computer's "estimations" of duty cycle. Unless you're seeing lean out on a wide band O2 then you're good.
