I swapped a friend of mine my stock exhaust manifolds for his set of Dynomax ceramic coated headers and will sometime soon put them on. But I have a few questions.
They are pretty nasty looking, a little surface rust and mostly dried on mud. What should I do too get them cleaned up a bit? I wanted to just spray them with some high-temp flat black, but need to get them clean first. Sandblast? Or jsut let htem socak in parts cleaner? Other suggestions?
Do I need special gaskets, like different from just the regular exhaust gaskets?
SHould I buy new bolts? The guy at Ho'reillys said I should find some that are "locking" and won't back out.
Thanks
