Turbocharged Desoto hemi for 67 Valiant

It looks to me like the wastegates installed incorrectly? Exhaust pressure should go in the bottom against the valve head. It looks to me like the exhaust is plumbed into the side. Hard to tell in the vid.
I was just mocking up the hoses and cutting them to length then. I had to tear down the motor completely to do some machine work in the block. The roller lifters were too short to reach the cam, so I ended up milling down the top of the lifter galleries to clear the lifter crossbars.
