With that much compression you need the highest octane racing fuel that you can find 116 should do it. With 200lbs I have too run at least 100.

You should be fine with vp110 or C12. I wouldnt run anything less than 110. Also with that high of compression I would check your squish clearance just to make sure every thing is right
