Another small block turbo early valiant

Don't know whether I can contribute to the thread but I remember the topic about manifolds/headers for a turbo application from a few threads...
I do remember that people were building the hot side using these: 94-04 Dodge Ram Durango Dakota 5.2/5.9 V8 S/S Racing Manifold Header Exhaust | eBay

Thinking about it they might be mighty tight in an early Valiant though...
