440 Duster headers

I just had this conversation with Ken Lazzeri from Indy cylinder head. I was told any headers for the -1 heads in an A-body are custom,no production headers available. Indy EZ's,SR's, Edelbrocks and others have headers available but not for the -1's.

are you sure about that?

I think Ken is wrong on that. -1's have the std 440 bolt pattern correct?

Hedman makes a header for -1 heads in an A body. #75161
