At 14:1 you need to run at least
108 octane.
Either Sunoco Supreme leaded(110) or VP C12 leaded(108)
You won't find a stock unleaded racing fuel high enough to run 14:1. You'd have to run leaded, and if you have cat's forget that.
I run VP C12, it's easy to get and it's cheaper than Sunoco. It's also more consistant. I can also buy smaller quantities.
The cost is $5.05/gal
At 11.5:1 you'd want around 104, and you may find some unleaded that high somewhere.

14:1
presents a whole boat load of problems.
Like finding a headgasket that won't disintegrate every few miles.
Fuel, obviously.
Starting, and turning the motor over takes a heap o' work.
Rods gotta be the strongest. Bearings too.
It's nice to wish for things somethimes, like having a motor with bunches of horsepower. But, you gotta think of the entire package.
