HOLLEY SNIPER FUEL INJECTION ~or~ CARBURETOR???

These are all very helpful and I appreciate all comments.
Let me ask, my kit says unleaded fuel only, but I’m up in between 10 & 10.5 compression and a .567 lift roller cam, 93 octane just might not be enough so now what?? No race gas or av-gas?? Is this motor too much for what Holley offers currently??
