Hahaha no! An experienced tech can do them in a good 6 to 8 hours.

are there any full length headers that are easy to install???

mid length? Do you mean long tubes? They have Long tubes and shorties. They are both very difficult to put in,

so what happens if you go with a stall converter or change the clutch? (Depending on whether you are auto or manual)
1)Long tube allow the velocity of your exhaust gases to not be interrupted and since headers are way thicker than the exhuast pipe walls, heat is better retained in the headers for more efficient scavanging. In other words better flow and scavanging characteristics = more power
2) MAC is also good for long tubes... (I would not recommend their shorties though)
3) On a stock GT with no other modes probably 15-20 hp at the flywheel. Some will argue it will be more but I'd like to see a dyno sheet to prove that otherwise
4)no experience so no help there.

<P>I appreciate the insight on the headers. I have to say that welding instead of bolting together is not really significant to me, because I am not planning on doing any removing afterwards. Now for some more questions.</P>
<P>1. Why do long tube headers work better than short ones? It's the other way around I'm told w/Z28's and T/A's.</P>
<P>2. What about MAC long tube headers?</P>
<P>3. How much horsepower/torque am I looking at with this modification alone?</P>
<P>4. Would someone be so kind as to rate these bases on quality, price, and bang for buck value: BBK, JBA, Mac, and Hooker. Thanks again. I need some more infor on Hooker if you can get me a link MustangMiguel.</P>

LTs make more power than manifolds (and shorties) because they have equal length tubes from each port, they have larger tubes overal, and the flow path is much smoothed out.
Scavanging happens when you acutally create a slight vaccum in the combustion chamber from your exhaust. It helps pull the burned gasses out of the chamber.
+1 on the rest though, and LTs for the win. Shorties are useless on a N/A boltons car.
