well tomorrow im gonna put on my header. i have a 2.4 stock header for my 2.2, and when i take it off am i gonna need to get a new header gasket? and is there a gasket in between where the header connects to the downpipe? i know when i did the exhaust on my truck there was a gasket between where it connects. i kinda figured i couldnt reuse the exhaust mani gasket, so where could i buy a new one at?
