thank you for the pics, they are worth a 1000 words.

they look almost exact but a couple slight changes maybe.

the pass side looks like a match,

the driver side has the tubes arranged a little different but look close enuff...#7 tube seems to be out of the way of the starter.

I think I am good with the 79170

I am hopeing that changes down the line are the differance between your pics and the advertising pic for 78170 headers.

big help and thank you.
