I just bought a set a couple of weeks ago. They fit a B engine A body perfectly- I wasted my $$ trying to make B engine headers work. The nickle chrome ones look nice and save about $200. I'm not worried about blueing- two reasons, 1- it's been dyno'd so the tune should be pretty close and 2- I like the bluing look. As far as the cost, they are well built and if there was that much margin someone else would be knocking them off. I've learned my lesson no more cheap headers.
What tube size ones did you buy?
The full length 1-3/4". They are a little small, but I have a stock stroke 400 and it's a street car with a full exhaust (Pypes 2-1/2" X pipe). I looked online and found calculators that recommended anything from 1-5/8" to 2-3/8"
for the primary tubes. If I have a 500" motor I'd want bigger but since Andy F made 550 Hp with a 470 and cast manifolds, I don't think I'm giving up much.
