Header's for a 67 cuda with a 360 magnum block.

We put some coated Doug's over the centerlink headers in the kids Duster. They were by far the best headers I've ever installed on an A body. Thick flanges and pipes. Only complaint is 1 and 5/8ths but with 360 hp that's all we needed.

I have been 10.68 with the Doug’s and car isn’t light.
they will support a good amount of power
