A friend was telling me if you think about it when they first built these trucks, they put the vacuum lines there for a reason even though we can void/not use them as for pollution prevention.

The only vacuum lines you need is distributor advance, transmission (if TH350), brake booster and pcv valve. Any other vacuum lines do diddly squat.

If you want all the things you are saying then you need a vacuum gauge and find out the reasons why you have poor idle and brakes for. These things are usually a worn out engine or vacuum leaks somewhere.
