Sea level? You're at 370' or so, my place, the highest in the county, is at 410'.
At sea level run 155/55 or 152.5/52.5 (preferred as the first combo will be sooty). From 200' to 4000' run 152.5/52.5 or 150/50, either is fine. Above 4000' leave the jets alone.
I grew up riding in real mountains, the Cascades and Rockies. I despise fuel injection, so got fairly tolerable at jetting swaps... 🍻
