Wanted 67 or 70 ported,exhaust manifolds, intake, good heads cast iron

I’m looking for 1967 or 1970 Ported exhaust manifolds, but I’ll take unported. Also need ported intake manifold and good iron ported heads. Trying to build a FAST car, it has to have cast iron manifolds. I'm located in Stafford Virginia 22556, 50 miles south of Washington DC.
