I have Hedmans on four cars and Hookers on two I'll have you know... :toetap:
Heard lots of good things about Doug's Headers for LA-Powered A-Bodies too; similar design as the TTIs - tie rod doesn't run through them so they don't hang down looking for a man hole cover to catch on...and two-thirds the price...

The nicest set of headers I ever saw were on my old motor home. They were jet coated Jardines, I just looked and all they do is bikes now. Times are changing :yesnod:

Ray is right on the money. tti's are great street headers but do not have equal length tubes. This will make them less effective on the strip but you won't notice it that much on a street car. If you are a serious racer then Hooker headers are a fine choice. I went with the 1-7/8" tube diameter after consulting with tti on my engine/drivetrain combo. Since my engine was modified with a healthy cam, compression ratio and induction system they recommended a bump from the standard 1-3/4" primary tube size up to the 1-7/8" diameter. A stock or nearer stock 383 is recommended to use the 1-3/4" primary tube size.
Sam - yes I have the tti headers. I bought them back in '03 after trying 2 sets of Hedmans that were, by admission of their own engineer whom I spoke with on more than one occaision, manufactured incorrectly. They would not clear either the standard nor mini starter as one of the tubes was in severe conflict with either starter.
Well, I decided to pony up and try the tti's since I had been reading about them in the various Mopar mags. They were expensive, but as Ray so succinctly observed "you get what you pay for". I also ordered the full tti 3" exhaust system with H pipe and got my Magnaflow mufflers from a place in Canada. Surprisingly they had the lowest price of any domestic suppliers. Go figure.
When moparmoose3 (Jerry) and I went to install everything we lifted the car up on jack stands all the way around and put the headers in from the bottom. I removed the spark plugs but left the manifold studs in place. The instructions mentioned that the engine might need to be lifted by 1-1/2" or more but we decided to try installing the headers without lifting the engine. We tried the driver's side first since it was a tighter fit over there. I as under the car trying to get them to fit and Jerry was up in the car (he has a bad back and we didn't want to have him all stove up - he helped a lot with disassembly though). The headers would only go so far and then they would hit something - which after a quick check turned out to be the pitman arm. We were chatting about it and Jerry all of a sudden said "wait a minute!" and turned the steering wheel all the way to the right - which moved the pitman arm all the way to the left. When he did that the header slipped right up into place as sweet as could be! We then proceeded to the passenger side and he turned the wheel the other way and the header went right up as pretty as you please. All told, even with the bit of trouble on the driver's side, it took no more than 1/2 hour to 45 minutes to get the headers in place and bolted in. No dinging, no swearing and no bruised knuckles! We then installed the rest of the exhaust system and Jerry just could not believe how easily it all went in. He had put Hooker Super Comps on his '66 Coronet with a 440/727 prior to my installation and it was an all-day affair.
The 383 4 speed installation was very easy but minor mods need to be made to the automatic linkage for 727 equipped cars IIRC. Their website gives all the pertinent information.
Overall I've been extremely pleased with my tti's. They are made well with 3/8" flanges so they don't warp and they provide excellent gaskets that don't burn through. Yes, they are expensive but IMO they are well worth the $$$.
How they would do with a Hemi I have no idea but if their 383 headers are any indication I would think they would be easier to install than just about any other header on the market. As for the 440 - well you may need to jack the engine up a bit since the 440 is a bit wider than the 383 but I think it wouldn't be all that much more difficult than my installation - especially with a 4 speed.

Okay - now for something completely off-topic...but reading this thread is the first time that I have seen it...
Bob, that is THE BEST avatar photo that you have come up with yet...
I had gotten quite used to "Wilson", so the kid peeing on the wheel seemed a little odd to me everytime that I saw it, but the tail shot of the B5 Hemi Car - now that is the proverbial "Real Deal"... :yesnod:

Doug Thorley has been around a long time. Sounds like they fit pretty well. How hard/easy is it to change the plugs and do you have problems with the plug boots being burned? I'm running Accel plug wires and have no problems with plug access or burned plug boots.

SAM Z.....headers or no headers....what did you decide??

Those look great!
I came by your car several times at Carlisle hoping to run into you but no luck...
