yea thats what im banking on....mid 12's....due to me not having the chance to measure the deck height im going to just go with a bit thicker gasket to assure im in the low to mid 12s. I will be running 90 octane mixed with avgas (aviation fuel 100 octane leaded) on a weekly basis to keep the mixture around mid 90s.

Your O2 sensor isn't going to like that fuel very much.
