At sea level I was at a 350 main 30 pilot 3rd or 4th clip with my ported 4mil with pods....... so you are close. Experiment with different sizes for each position (pilot, needle, main) until you get the pull from the engine you like. Only do one position at a time though and one size at a time.
Oh and one more thing...prior to doing any jetting take a can of carb spray and clean out all ports on carb especially the pilot. If it's dirty you will be chasing your tail all day.
