I need help on getting the right flange gaskets as mine have crapped out. I am not sure where to buy them or to get a part # because i used the crappy slp ones that came with it. (the larger header gaskets blew out a long time ago by the way). Does felpro make any gaskets like this for the flanges? All the help i can get would be appreciated as i am going to knock this out as i change the passenger side spark plugs.
