Ron, it is hard to imagine much better ground clearance but I like the oval 3" collector. Here is a pic of my first run headers both when I got them back from Jet Hot and on the car. My oil pan is actually lower than the primaries. The collectors are a bit lower than they should be as I had to drop the TKO down 3/8" to clear the tunnel. :

Nice headers Steve but they only closely resemble mine now. There are so many mods in key areas that make a world of differece in fit. The most obvious on the D-ports are those flanges. They have been redesigned & a lot easier to install the header & better port alinement. Those flanges on your set & are also the same ones Doug's still use today & are a poorly thought out design. They can be installed two different ways & clearly they didn't have any clue which way was best. You can see that from pics of there different headers over the years. Some had then one way some had them the other. If your a Pontiac guys you can see why but to a place that builds mainly Chevy, ford & other brands of headers it was probably the best thing they could come up with.

Im sure that it would have cost me another $1000 for a one time 5min of work on there end to mark it on the jig so that all 4spd headers wouldn't be screwed like the autos were. Not to mention another 1-6 months for them to do it. I compromised way more than I should have had to on that run but they were holing ALL the cards & I still didn't have a pair.
