Hi, welcome to the board.
You'd probably be better off posting your question in the appropriate forum. (Engine for this question)

Personally, I think you're dreaming there buddy, but maybe one of the other guys knows better.
You should read this tech note at kb-silvolite for more info.
PUMP GAS (regular)
8.5:1-Non-quench 2 valve head road use standard sedan, without knock sensor.

8.5:1- Quench head engine for tow service, motor home and truck with torque cam.

9.0:1- Street engine with proper .040" quench, 200� @ .050" lift cam, iron head, sea level operation.

9.5:1- Same as 9:1 except aluminum head used. Light vehicle and no towing.

10:1- Used and built as the 9.5:1 engine with more than 220� @ .050" lift cam.

10:1- 4" and smaller bore, high RPM cam, cold plugs, good fuel distribution, full power limited to 30 seconds W.O.T.

RACE GAS
13:1- is the highest compression ratio suggested with unrestricted gasoline engines.

13:1- Plus o'kay with restricted intake engines at high RPM.
