Other wastegates with a single hose usually have a long actuator rod, and the diaphragm mounted on the cold side. The green book "design and function" goes into depth about the design/importance of the wastegate cooling system, but I can point out several other obvious mistakes/misunderstandings printed in those books.

Did you use the stock exhaust housing and wastegate to build your new turbo?

way way way over thinking things is what I *always* do- I can't help it, but it's kinda fun too
