They are the same exact headers and I had aluminum 87 e heads on before with the old setup. They are DHE-D581 round port hookers
Also is there a different brand of header or anything I can do to fix the problem??
Thank you as always!

I think you answered your own question. The only variable is your motor height.
Headers from the same maker are typically identical as they are machine bent and jigged prior to welding. If a difference occurs, it is fractionaI and the result of sloppy assembly. I recently replaced my headers with the same part number as I was happy with the originals' fit. The replacements fit exactly and when bolted up, even my tailpipe alignment in the valance panels was unchanged.
