Thank you so much for sharing that. I was going to go with headers as well
but will now hold off for a while and do other mods first, at least until
someone has a more positive experience with headers on the 4.7L. I'm sorry
it was a waste of time and money for you. Like you said "live and learn".
Once again, thanks for taking the time to share you experience with us.
