That said, I'd just swap with 2006 trailblazer or 2010 camaro manifolds. As long as they are still equipped with the heat shields, they look very close to stock. The only way someone will know they were changed, would be by checking part numbers. I seriously doubt that happens.

Well here in California I will have to go through a referee station to make it a legal engine swap and they just might check everything. Never done it before. I know about notching the frame but I thought it was for early manifolds with EGR. Not a big deal to notch the frame but would rather not if I dont have to
