i did a search and was reading some of the old threads and i came to the conclusion that i am going swap out the copper gaskets that came with the mac headers and going with the felpro. i have that ticking noise and im hoping this will solve it. i wanted to ask if anyone knows any good tips to make this go smooth as possible. also, what tools or wrenches does everyone find to work the best. my bolts backed out a little while back and one even fell out. i originally had some buddies of mine do the exhaust and i guess i never made sure to check them after a few heat cycles. i know that when i replaced the one that fell out and when i tighted the loose ones it was a huge PITA with a 7/16 ( i think thats what it was) wrench. any suggestions, thanks.
