Mild Built 340 Timing/tuning help?

I have a similar build. 30 over 340, 10.2/1 with the comp cams X285HL air gap with 2.02 J heads. Run 91 all day long, most of the time I run non ethanol 91. Timing is set at 16 base, 35 all in at 2800. When I get my poop in a group, I have ported Eddy rpm’s and air gap on the shelf with will bring it up to 11.5 - 1. Still going to run pump gas…0

110 at over 10 bucks a gallon in a waste, granted I do like the smell of race gas. My brother runs the vintage Cosworth BDA 1600 race engine in the mid 12-1 range but those things are spinning 10k rpm. Race gas in the pressure washer works well
