Default C4 1984 coolant drain plug on motor

I got a 1984 corvette and i had a head gasket blown up, and so i removed the heads, i sent them to get shaved, but now my dilema is that i dont find the drainplug for my coolant. I did open the oil drainplug and removed the oil/coolant, and removed oil filter, did not open the oil pan, just drained the car in a angle so it has nothing l3ft in it. I will wash the engine with diesel by puting it through oil chanel on top of the head, but i still did not find the coolant drain plug. Please help me.

Pull the knock sensor and there should be a similar port on the other side, you can also pull freeze out plugs but that get Laborious.
If you're also looking for a drain on radiator that is on the back face of the tank.

The drain on the radiator (at least on my 96) is not hard to find. Dan
