IMO, you're right on the edge; .040" quench and you'd probably be good with 93 octane. My numbers are real close to yours, but I've got bad air here and only 91 pump. I'm also still tuning, but I do currently run a 3/10 gal. race/pump mix just to be safe. I might be able to go with straight pump after I get it dialed in.

I believe +15* is to be added to the @.050" number.
