I have a 6 litre to go in my 65 and I was planning on using the cast iron exhaust manifolds. It looks like I have a ton of clearance with the frame rail. They might hit the motor mount but not the frame. They look very similar to yours but not exactly (mine are from a SSR). Where exactly are you hitting?
Thanks,

PS. I was going to use header wrap or something on mine. The cast manifolds are pretty hard to beat power wise. In the tests I have seen the headers can usually barely match the cast iron on LS1 / LS2.

Yeah, some of the stock manifolds flow very well - especially the Vette's. Your motor must be sitting higher, because the manifold on mine just comes down too far and hits the rail all along the main runner. It(header) needs to be either closer in to the motor or not hang as low.
Header wrap should do the trick for heat.
