Well, see what you get after the new adjusters arrive. But still...your motor probably wants at least 91 octane, especially if you plan on putting your foot in it. It will run with 87, but you won't be able to run as much advance, so your EGTs will be higher and the performance will also suffer. Keep in mind, the motor was designed to run on 87 with the original pistons in place. You've raised the static compression, so you should make some allowance for that; at least run mid grade, lol. Also, the louder your top end is, the more likely the knock sensor will be fooled into (further) retarding the timing.

Again, glad it's running for you.
