Personally I would prefer we discuss the general motor and carb modifications that still delivers great tq at lower revs.
The limiting factor in going with a higher compression is simply valve clearance. There is a balance in how much compression you can gain before you start banging against the valves.
I think that you will run into pre ignition problems with higher compression before valves start hitting the pistons. That will move you into racing type fuels or ignition mods pretty quick.
