Old Exhaust Manifolds or Headers

Hi guys,
I’ll be building a 416 stroker soon and I ordered a nice shiny new set of TTI ceramic coated headers for it. However, TTI recommend that I use an old set of manifolds or headers for the first engine run/cam break in to avoid wrecking the new ones. Anyone in NC got an old set laying around that you want to get rid of?
Thanks, Bob
Yes I’m in Youngsville near Raleigh. I have several sets.
