Headers for Indy 440-1 Heads in a Duster??

The Indy 440-1 heads have raised exhaust ports that prohibits me using my current headers.
My victor knock offs have raised ports, and I run a used set of TTI headers I bought off a guy from Witchitaw, K,they are very close everywhere but fit. I do have an aftermarket front end w/ no torsion bars tho.
