I see this story never ends, I posted several times last year. I went with TFS heads and Dougs and man they don't even look like the same header after I beat them up.They hit everthing! Still not sure if the TFS exhaust port is higher or not. I used those thick motor mounts from a Dart Convertible also. Had to raise the motor, Just buy the cheap Ebay stuff it won't hurt so bad when you take a hammer to them, you know going in what to expect.
