If you’ve gone from bog stock to all this in one go then yes, you should notice a difference. However, if your engine is high mileage, low on compression and generally a bit worn out, the effect will be proportionally tempered.

On a stock camshaft and old engine, the spacers, throttle, and chip in particular won’t necessarily be noticed by ’feel’. The rockers and exhaust mods should give a crisper response and feel though.
