I would think with a jd kit, you will be fine. I was shocked when I opened up my 01 300 when I did a ltr jet kit. Mine was jetted oe for leaded gas...
It had a 35 pilot in it, which I had never seen before. I am about the same altitude as you and have been switching between a 42 and a 45 pilot. The ltr kit came with a 45, which I (insert dummy here) thought would be too rich, but seems to be fine. I think the main is a 170 or 175, don't remember for sure. I am running the oe needle, center clip.
