I will second the Banks stainless headers. Put the Power-pack on my 95 454
Burb and was well pleased with the results. 165k in snowy-salty western NY, The only fault I found were the mild steel clamps which I changed out at install. For all I know the new kits may have all stainless now.
This is one very good US product, with excellent customer service>
