TTI makes a 2 1/8 stepped header that they list as working with the victor head. It's the one they list for a stage VI head as well, as both have the exhaust ports raised .250" and extended .300".
But, they also say you have to bend the passenger side header out a bit as they say as it contacts the block on that side.
Not sure why they don't just make the "adjustment" so the customer doesn't have to.

That said, I'm running hooker super comps with the victor max wedge heads on my coronet. They were already "clearanced" in a few places to work with the rpm heads heads and just needed a little more tweaking for passenger side torsion bar clearance when I switched to the victor heads.

70blackfish is running victor heads in his e body, but I don't remember what header he's using. Maybe he'll chime in.
