TTI Header ID Help Please?!?

I scored a set of brand new TTI's today at a swap meet. The guy said they were for a 68 Barracuda with a 340, so I know they'll fit my vehicle. My question is which one of these headers did I buy?

TTI Small Block A body headers

Here's some pics.





They are a ceramic coated step header, but I can't tell if they are coated inside or not. It looks like it near the head flange, but not at the bottom flange? Are these polished or just the plain coated headers?

Thanks for any help you can provide!
