who makes if any ss risers to bolt on to the stock 496 ho manifolds?

Sonic, you can polish stock SS risers with a little patience. I did mine long enough to match my intake, but I've seen pics of some that look perfect! I used aircraft stripper to remove the paint; a plastic sanding wheel in a drill to clean all the welds (this part sucks); several rounds of stainless polish and a mothers ball. If you don't have the time or patience, i'm sure there are several "metal poloshing" companies in your area. Good luck!

If your looking for an extra set, I do have a factory set of black SS risers. PM me if interested...

As he said you can polish your risers as they are stainless. I did mine as well it just takes some time.

thanks guys i'll try it

There is a set currently on ebay
