with the truck manifolds, you have to relocate the alternator and the A/C compressor if you wish to keep that stuff.
truck manifolds save alot of time too, less stuff to fabricate for your hot parts. Also won't have to worry about them cracking. You can also get to the spark plugs very easy with them.

the truck manifolds are the best as far as strength but you'll lose your a/c and power steering, you'll have to relocate your alternator as well, which is no big deal... but I've always considered them race headers because they retain no creature comforts.
definitely for racecars only. It would be sweet if someone made us some cast iron manifolds that just came straight forward on the outlets, instead of downward like the truck outlets. That would give us some more options, maybe like bolting up the turbos directly to the manifolds. Someone make those!

the ohio boys said they had to fab something up as it melted off or something like that. only thing i think it could be is one of the slip joints or something, i might just insulate that and see what happens, hopefully it holds up.

I guess my question was vague, because I already know about cast manifolds holding up better. I was really wondering about scavenging and reversion back into the ports.

You loose A/C and have to relocate the alternator to the top.
The power steering lines have to be either bent in a way to clear the manifold or have new ones made. I was able to bend mine around and has not been an issue. Now as far as the steering shaft goes. It is close to the manifold and I was originaly going to make another shaft like I did on the Formula. But I have been running the stock shaft with the manifold heat shields in place and have not had any issues. These manifolds do glow red in high power/load situations. 
These are not "race only". Ask me how I know?

Because of rigorous street duty testing like this.

I might just give building my own headers a shot. With some bends and some flanges, could only cost about $300? I got all winter to do this bad boy so time isnt to much of a concern. If not i guess i really dont need A/C. What do you use to relocate your alternator?

Yup old post but I am doing research.
Has anyone used Flipped GTO headers? We have to flip them to use the GenTT twin kit and we lose nothing. and about Nine Ball's comment of the outlets. The GTO headers are just that. I was going to use fliped up GTO manifolds to run a twin kit. However I need to make a adapter to pull the drivers side header forward cause it hits the brake booster.
