The header tank should be operated with an air space above the coolant, never full.

The header tank should be the highest point in the cooling system.

The header tank will only burp coolant if the coolant level is too high. The header tanks in the last 2 cars I've owned did not have recovery tanks. BUT it wouldn't hurt to have a recovery tank if it would make you feel safer. Some race tracks or racing associations may require a recovery tank.
