more out of 5.9l 360 magnum

Dougs or tti headers are all you'd need. I like Dougs because they work, fit well and are ~250-300 less expensive than tti. The 1 3/4 step headers just don't provide enough benefit for the extra expense.

True. But being 1 of 2 headers designed to fit nice and they work very well, it just kind of really stinks that they were not designed this way back in the day so that perhaps, perhaps they cod be an inexpensive design header to purchase today.

The tti affords a higher ceiling mevel of power while working well on lower powered engines.
I'd like to see a dyno shoot out between them. Interesting thought.....
