The 1-7/8" headers should be fine with a mild build.
The Chrome plated ones are $691. Not sure why the bare ones are not cheaper than $671?
They are $841 with the ceramic coating, and $870 polished? Man that adds up quick...
The initial cost is steep, but everyone I know that is running them have no complaints.
I'm running old Hooker 2" supercomp headers that don't fit well (low deck with Victor heads), are rusty, and have exhaust leaks. When I get the money, I'm changing to the TTI's they make a header specific for low deck bigblocks with raised exhaust port heads.

That's for a 67... I think they use a different resivior...although I had them on my 67 coronet w/ no issues.. wierd.

Actually it lists for a 67 Coronet because that is what I did the search on summit for. If you check for any b or e body car, their site will state they won't work with p/s.

Guess you proved them wrong.

Thanks everyone for the great replies on this topic. This will help me with this build.
