honestly, I think you're going about it all wrong.
The engine you have is built to very mild specs. The only thing I'd look at doing for a daily driver is swapping to a good fuel injection system- it can really tame the engine.
A well prepped and tuned carb can come close to a FI system when everything is warmed up and you have consistent weather. But for ever changing real world conditions EFI makes a big difference in both mileage and drivability.
