Ive Seen That these are the top 2 Headers. I have a Small Block 360 that should run high to mid 11's. Which Header is best suited? Or Should I just Stick With the Basic Flowtechs that are already on?

What is the difference in all the coatings? Specially the Polished ceramic coating outside only and ceramic with thermal?
Bigger isn't always better.

Agreed, How can I tell which would fit my needs? I already have 3in exhaust and possibly will port the heads further in the future

Wow, those are expensive. I think perfweld is a member here on the forum.
You won't see a noticeable difference in power using either Dougs or tti.
Like your tires, make a choice and go.

Thanks, TTI it is....
dont just look at the price look at the details in the pics,there is one single thing that realy stands out to me,that makes alot of diference compared to the brands available in a box from the regular places.

It seems that people are leaving out crucial information when it comes to choosing between Doug's and TTI.... your transmission. If you run a 727, you are forced to go TTI since Doug's will hit. If you have a 904 or manual, then Doug's will work.
they have the 3" collectors wish will fit the rest of your exhuast slightly better but you will probably need to work some anyway to make your exhaust fit with the new collector location.
thermal barrier or just ceramic coated, well the diference is that the thermal barrier is there to keep the heat inside the tubes,adding velocity to the pulses as well as keeping heat out of your enginecompartment meaning you will make more power since the air will be colder. it also saves the tubes alitle, mild still gets kind of hard welds get more brittle when being subjected to extreme heat and cool downs over and over again
i think there has been some threads on the 904-727dilema and i think the conclusion has been that dougs fits with the 727 as well, and im not 100% sure but i think dougs has there problems with manual transmissions clutchlinkages as well but im not entirely sure
Dougs fit with a 727. Many members on this site have installed them with 727 including myself. Dougs needs to update their info. I believe it also says they don't fit on 73+ cars either, which is wrong!
tti and dougs both have issues with the down leg of a Z bar on every car I've ever installed them on.

I have Dougs on my '74 with P/S and a 904. I don't see why they wouldn't fit with a 727, especially since many people have.
These are definitely out of my price range! Looks pretty sweet though.

What do you have to modify to run dougs headers on a 69 GTS 4 speed car?
Mad Dart
Nothing to see Here!
Seems that every car is different. I have TTI's on my 70 Dart/4spd and a Quicktime Bell. I had to fabricate my own pivot bracket for the Z Bar on the Bell Housing side.
