No the pilot and needle stay the same, I feel that 290 will be rich but it won't hurt trying it, you will be more in the 250-270 range with that setup, what's your elevation?
#270 to #290 main should be ok, plug chop to confirm.
If it runs a little rich, swap to 25:1 pre mix to compensate until you can get a smaller jet.
Leave the stock #32.5 pilot in there.
Needle in the middle slot.
Set the float level and adjust the idle as per specs and all should be hunky dory.
