Super comps dont fit!
I have the same headers on my duster but i used a moroso deep pan. I was doing to use a milodon pan but i had the same issues you have. I like headers for spark plug clearances. So me another header that you can change all the plugs in less than 10 mins hot or cold. I say buy a moroso or take your stock pan weld 2.5 inches into it. The headers will fit the chassis like a glove. Harry
