Review on Dorman 674 503 Exhaust Manifold Kit by Geoffrey Graham

Hot Rod Assembly. This distributor offered a solution to this problem. Shaping is good, a little natural/rough but quite heavy. This is a very good copy of the original at a great price. 2 1/2" exhaust pipes with heat pipe installed for those of you with an early carb that need a heat pipe to operate the choke. All in all a great purchase with all the necessary gaskets and hardware to install (minus the cylinder head bolts). PROBLEM: I've had them for a few months now and the bolt holes on the alternator/generator mount blew out quickly and I had to have heli-coli so get ready to do that
