Will someone please confirm?
On my system the end switches on all the valves connect to boiler on.
The boiler has a pump over run stat and connects to the pump.
You don't say what boiler you have or if you are changing it.
It may need an overrun stat if you remove the gravity loop.

The boiler is oil - about 5 years old. Not sure what you mean by
overrun stat. Please clarify.
