Mine will only move about 10-12 degrees, so I set mine at about 20 initial and about 30 total, but I am a little over protective of my parts, so I do not care to try 35 right now.
If I was you I would set it to 15 initial and 30 total and make sure it will not ping. If not then raise it to 35 if you want to. If it does not ping, then you should get slightly better performance with the 35 degrees. Your choice.
You can try connecting the vacuum advance, but there is a chance it could ping with the 9.5 compression. I leave mine unconnected.
