confusion torsion bars or no torsion bars

good afternoon friends, Im working on my 71 Plymouth Duster and i think im ready to order the TTI headers for the 400 to put in my car. the problem is ive been looking and talking with a friend of mine and he tells me i need to buy a elimination kit to get rid of the torsion bars as the long tubr TTI headers wont fit with torsion bars in so with eliminating the torsion bars and running coil overs it will work. But on the other hand i was talking to a nice gent on line earlier today was telling me you dont have to eliminate the bars they will fit. I dont have a lot of money right now for this so im trying to figure out do i order the elimination kit or do i order the headers ? Any info would be appreciated. Thank You
I have 2-1/8 tti's and my torsion bars fit just fine.
No rubbing at all.
Does you friend have tti ?
