fenderwell headers

Does anybody run a fenderwell header in a "B" block (383/400) Duster??

I can't get TTI headers for my Duster, because they don't make a 2" tube for the stock head/ 383 or 400 block application and I am considering going to fenderwell style.

Any thoughts, ideas, advantages/disadvantages, suggestions...pix would be nice!!

Anybody know a manufacturer that makes a 2" tube headers that will work for a "B" block Duster??
