Yes, but the Dorman quality has suffered severely in the last few years. The ID of the standard ones are smaller ID and they ALL include the A.I.R. ports and I don't want that.
I am looking to install CORRECT manifolds for this truck, with the exception that I am eliminating the heat riser on the bottom of the manifold. I do not know which side originally had the the heat riser, as the truck that we have has been cobbled so much, I am not sure what is correct and what is not.
I want to be able to make this a pseudo-restoration, as we have most all matching numbers for the main parts and the under-hood paint is still original and the cab/front is in decent shape.
We'll start there, then performance modify later.
Thanks!
