Tips wanted for rebuilding a Q-Jet

[C10Silverado79]

So far I've replace the water pump, fuel pump, belts, hoses, shocks, and brake system (except MC - hard lines - vacuum assist). I think it's time to rebuild the Q-Jet. Any advise or Tips-n-tricks for rebuilding the carb will be appreciated. I rebuild a 2bbl on a 250ci about 18 years ago so to say I'm rusty would be a gross understatement. I'd prefer not to spend the $$$ for a rebuild carb if I can help it so I'll try the self-rebuild first.

Are there any particular brand of rebuild kits that are better or more complete than others?

Any "gotchas" I should be looking out for?

All advise is welcome.

TIA
