If you have decided to stay away from turbos and superchargers, there are still small things you can do that will get you a few horses here and there from the engine without breaking the bank.
Electric fans, if you don't already have them, are better at keeping things cool and you gain a few horses from removing the stock water pump fan.
Phenolic spacer plate for the carb. It will insulate the carb from the engines heat, allowing a denser fuel/air mix for more power and when tuned properly, gives you the extra power with increased fuel economy. (be sure to have clearance for the carb/air filter as they are typically 1" thick) SummitRacing has a good selection now starting at $26.
Crank scrapers either aftermarket or home made. They get all the excess oil off the crank, making it a lighter rotational force. More power and quicker RPMs. Although being very cheap, may mean hoisting the engine up a bit, or completely out for installation.
Wrapping the headers or exhaust manifolds. (WARNING - this will void header manufacturers warranties) Basically getting excessive heat out of the engine bay allowing a cooler compartment and cooler air intake to get a denser mix.
I have no idea what year your bronco or the engine it has, so I may have made some suggestions that can't be used (carb spacer already has electric fans etc)
Some things will work on any engine, such as getting excessive heat out as heat is a big thief of horsepower. Deburring a block and heads can give a small increase in power also, works on all engines yet is an engine out and apart type job that can be cheap if you own a Dremel and like to do all your own work, but it does mean down time and it sounds like you are trying to avoid too much down time.
I don't blame ya there, it's fun being taller than most and even I would miss the daily driving
