I can offer this bit of insight.
When I went to buy my trailblazer ss cast manifolds, the owner had a new set of long tubes for his tbss waiting to go in. He let me fudge around a bit and we looked, at the clearances to see if his new headers would work. The area where the headers overlap and merge is too wide compared to the cast manifold, at least in my application (66 with mount adapters, sitting about 1" forward.
