SST headers would be cool, especially if they fit right out of the box. I might be able to help you with the sticker shock though. I converted my '65 over to headers so my coated manifolds and head pipes are now just sitting on the shelf. The manifolds should work on your car but I doubt the head pipes would be a bolt in. If you want to run coated manifolds that are in pretty good shape I can sell you these for a lot less than $1500.

You still have my old 470 in your car? If so, these manifolds were originally on that engine anyway.
