With the work you've done, I think you need headers and maybe a 2" or 2 1/2 " exhaust with free flowing mufflers like Flowmaster or Dynomax. I had to install a 4 row radiator, Flowkooler water pump, Shelby front valance, and an auxillary electric fan before I got my '66 coupe down to about 180-200 deg F. Now it's always less than 200 F.
