Save your pennies and get a good set of Fentons or the alternate versions sold by Tom Langdon. For a street car you will be way happier. Use a rimflex gasket and you will be all set. I have run a set of old style Clifford long tube headers on my motor for nearly 40 years. I took care of them, cleaned and painted on a regular basis, but still they have their issues. The Fentons will do the job, give you less grief, and hold their value whereas the cheap so called headers I see on line for under 100 bucks are 100 bucks for a reason.
