That is called direct EVACUATION. Same as PCV- positive crank case ventalation.
You only see that on racing engines, It creates a vacuum and sucks the preasure
out of the crank case ( or engine ) Directly in and out of the exhaust system.
When a engine is running it builds pressure inside of the engine. That's what a PCV
valve is for, to remove the pressure. If you do not have one, then the pressure
will build up in the engine and blow the oil seals out. Then you have bad oil leaks.
seals and gaskets are the weakest points in the engine.
If you look at your engine it will not have a PCV valve, But that's okay just keep those hoses hook up to the headers. You have the best system now.
What else can I help you with?

Where is the heater control valve on a 1995 Astro and how do you replace it?
I have a 94 Astro but the heater control valve should be in the same location. Look under the hood on the passenger side. There are two heater hoses behind the coolant reservoir and windshield washer reservoir. The hoses attach to the heater control valve. The valve has a round vacuum actuator on the side, and two more heater hoses leave the control valve and go into the heater core housing. Cost for the valve will probably be somewhere between $50 & $70 To replace it, remove the coolant reservoir and the windshield washer reservoir. Remember, or mark, the hoses for the washer if you have a rear washer. The electrical connections only go on one way. Remove the clamps securing the front heater hoses and remove the hoses from the valve. Remove the clamps holding the heater hoses coming off the back of the valve where they are attached to the heater core. These two hoses are factory attached to the valve and the new valve (from the dealer) comes with the hoses attached to the rear of the valve. The clamps are back in a small space behind the valve, rather hard to get to. We pulled the bracket with the three square relays situated above the hoses to allow easier access. Install in reverse order. Good luck.
