This is very good information to read, I have the stock ram horns on my mildly built 350 but was going to install a set of headers I acquired form a friend. Guess I'll leave the ram horns alone if they are better than headers. I knew about issues with headers sealing but was willing to tolerate that if the performance was better...

Thanks for the info!
