While there is demand in the truck world for headers it's not near what the Fbody demand is and there are very few competitors producing true long tube designs. "Low" volume sales and lack of competition creates artificially high prices.

The AS&M headers are mild steel and coated. The dynatechs are stainless and don't really need to be coated but, need the proper maintenance to keep the stainless looking good. They won't rust through without the coating like the AS&M's would. The dynatechs also come with 2 new cats and a complete replacement y-pipe which makes the price a little higher.

Yeah, I just mentioned they didn't need to be coated cause they are stainless. They won't rust out like normal mild steel headers that aren't coated. 
I have had better luck LOOKS wise in the past with mild steel headers that were coated.

What type of gains did you guys see from these? Comparable to the other long tube brands?

Did I read correctly that Dynatech is shipping #5 and #7 wires that actually fit now? Mine did not even come close to fitting. I had to take some longer MSD wires I had laying around and cut them to fit. Also, I had the passenger side frame clearance issue with mine.

I have heard about the passenger(?) header hitting the frame, or being close to it. I contacted dynatech about it and they said they have built better jigs so the headers fit better.
With it having cats, and a y-pipe instead of duals, it doesn't open the exhaust too much correct? Currently the exhaust is stock except for a flowmaster with dual tips. Thanks in advance.

They are for the 6.0 and the y pipe is wrong and they have an egr hanging off the passenger header. Gotta get them swapped out. I have at least had a chance to look them over. I was impressed with the construction. Great looking welds and no slag and such left laying around. Kit came with 2 plug wires, gaskets, bolts... everything needed to put them in except perhaps some anti-seeze for the bolts.
Hopefully have this straightend out this week and on the truck next weekend. Dynatech must be having a big blow-out. I see lots of promotions listed here and other places. I got mine for under a grand shipped. Well almost got them
