When I ran my 416 I was close to sea level and ran a 175 main.

I just re-built a 400 for a friend and did a 416 10:1 with the stock filter, lid on and a full big gun exhaust and I tried a 165 and it was lean. I put in a 175 and it ran good. I haven't pulled the plug to check it yet since I just got it broke in Saturday, but I'll be sure to update this when I do if you still haven't found out what you need by then.
