Header question?

Saw a good deal on facebook marketplace these flow tech headers 12104FLT were only 50$ and was wondering if they would work with my gt40p heads. Just curious to know if they have clearance issues or anything.
 
The flowtech headers are the same as the summit brand. I have a set of long tube flowtech headers that have been on the shelf for about 8 years. Are they long tube headers ?

The only brand I know works is bbk....that's only because I've actually installed them on gt40 heads. At 50 bucks you can't loose if they're in good shape. Could always sell if you don't use them.
