T.T.I's vs. ........you be the judge
Ok, did some A-body specific research. For an A-body small block the Hooker Super Comps in 1 3/4" only are listed as fitting the '70-'72 Darts (although I would imagine they would also fit the other a bods from these years), this is part #5204. The ceramic coated ones sell for $750 from Summit. The Hooker Super Comps for '67-76 A-bodies are part # 5116, but these are a 1 5/8" primary tube, and are listed at $690 at Summit.
So, for an A-body application the article is pretty useless. They didn't even test the 1 5/8" Super Comps (5116), which will flow different than the cheaper competition headers they did test. And the 1 3/4" tube Super Comps (5204's) are pretty limited in what they'll fit.
From Magnumforce the TTI ceramic coated, non-polished headers are $718, same price for the A body and the B & E body versions. The 1 3/4" ceramic Hooker Super Comps for B & E bodies are $690 and there is no 1 5/8" version for that application, so my E-body info doesn't totally apply. But neither does the info in the article, as they obviously weren't using A-body headers.
Sooooo, for A-body's
Hooker Super Comp's 5204, 1 3/4" - $750
Hooker Super Comp's 5116, 1 5/8" - $690
TTI 1 5/8", non polish ceramic - $718
polished - $748
For everything else...(B,E,F,J,M)
Hooker Super Comps 5115, 1 3/4" - $690
TTI 1 5/8" - $718
