First off welcome to the HQ. Now for jetting IMHO I think that they will still be too small I woulkd start with at least a 360 and then do a plug chop to get it perfect. When tuning its always better to start rich and then lean it to where it needs to be. An engine will run its balls off with a lean condition until it melts down. So do your self a favor and tune it correctly or you'll burn it up.

320 and 27,5 pilots will be a great starting point. 360s are way to much fuel.

you might want to see if you can get the jetting from about 280-340. That way you will be ready for mostly all temps
