Manifolds

Was at a show yesterday, and met a guy with a bad *** black 68 dart with a 383 in it. He was running factory B body coated manifolds with no clearence issues. He said the B body manifolds clear just fine as long as you are running a low deck 383. Just wondering if anyone else is using this same setup? I never heard of anyone using this setup, I thought you had to have BB A body manifolds or headers.

Thanks Jeff
