What headers for 318 magnum in an A-body?

All the 3 tubes under the front end linkage headers suck for fit. Some of the best fitting headers I have had of this style are also some of the most offending fitting headers I have had.

Quality control of these basic 1 size fits all header is poor on it's best day.
The summit headers fit best, bar none on my old Duster. While the same header a year later was the second most horrible thing I have ever had the displeasure of cutting and denting.

Hookers are said to be the best. On my Duster (Last one) they fit OK. There was a fitment issue at the power steering box's mounting bolt. I had to revers the bolt in order to fit them on.

The up most worst were Black Jacks on my first Duster.
The best were the Hooker Super Comp headers for my E body 4spd Cuda, but they are not the style above.

The best fitting headers are Doug's and tti's at a steep price. While worth it, cost may be an issue.
