I have the 5.0 with some mac headers and i have blown a set of material gaskets in about 5,000 miles....When i first put the headers on i used the copper and they leaked too much for my liking. I read the threads on the horrible design of mac headers. Not sure if that could be the problem or what. Those with the 5.0's no what a pain in the butt it is to work on these.
Curious to see if anyone has some remedies or just your opionons on the topic.
