I would spend the $100+ on the stock carb rebuild. Once you start replacing the intake/carb/linkage/aircleaner with non-stock items you open a whole new can of worms. This is one instance where stock equipment is the best choice in my opinion.
If you were heading down the road towards a high-performance engine build I'd say go for the aftermarket intake pieces. In this case it sounds like you're more interested in a good running stock engine for a daily driver rather than a faster/more powerful modifed one.
For better get-up-and-go I'd intall a good stock 250 engine in place of the 194. Good luck.
