High compression with aluminum heads and pump gas???????

Renegade Fuels recommends 11:1 compression with their Hot Rod 102 octane unleaded. So that is a much higher octane rating than premium pump gas and they only recommend 11:1 compression ratio.

I'll have a 10.5 CR big block on the dyno in a few weeks. We'll probably be using the Hot Rod 102 or maybe a mix of it and pump gas. I wouldn't run it WOT on just pump gas. I just don't think pump gas is good enough for a big bore engine at 7000 rpm, especially without any of the electronic crutches that the OEM's have.
