Big block HP exhaust manifolds

Big block HP exhaust manifolds in good shape casting numbers are 2843992-2 and 2806900 I was going to use them in my 440 duster but found a set of used Schumacher headers instead. They are not boxed yet and I work full time so it may take me a day or two to get them shipped.
