A. Can you be sure you can get high octane fuel EVERY time you fill up? Raising the compression ratio then using lower rated fuel (even just once) is a recipe for disaster.
B. It's not just a case of milling off material from the heads. Depending on the deck height of barrels, the heads may need different amounts machining off them. (The barrels aren't always the same height!)
C. Unless you have the full spec's, I would stick to standard compression ratios. They will see you well into the high 60's if the rest of the motor is set up properly.
