Back in the day, I bought some headers for my LT1 and they sat in my garage for a month or so, and then sent them off to Polydyne to get them coated. Fortunately they had another pair they were about to do for a LT1 and said they did not look like LT1 headers. I took them up to G-Force and they were LS1 headers. The seller had no clue and refunded me money instantly.
I guess it just comes down to the seller you are dealing with...and it seems like you're dealing with a hard headed one. We're all car enthusiasts here and are here to help each other out. Hopefully he does the right thing. Good luck!
