School me on 340 exhaust manifolds

I know I can be quite opinionated. I'm sure some people can agree with me if they have seen some comments I have posted throughout the site.

However...most of my opinions pertain to the OP questions.

Had I been asking "IF I should buy original numbers correct manifolds for my car". Then some of these opinions would be valid and should be considered.

That is not what I asked. I asked to be taught about 340 manifolds and how to identify them. Therefor. The fact that one might not understand me as to why I would bother, and make comments like "good luck with that unicorn that only Barrett Jackson will care about."

These comments are as Not relevant to this thread. It would be the same thing in the for sale add and your comments saying it's too expensive arnt welcome as stated in the rules.

Am I asking too much?
