tti vs. Doug´s headers

I have a 440 with Edelbrock heads in my ´68 Charger, Power steering 4-speed.
And I tried Summit Racing headers. That was a big mistake. These headers a really crap.
Now my question: What headers would fit my combination best? I don´t want ho hammer on the ceramic coated tubes.

Flip a coin on TTI v Doug's, I have Doug's D452's on my 69 RR w/440, power steering & 4speed also, fit like a glove, no hammer required. :2thumbs:

I'm not a header guy and offer no suggestion, but I sure like that picture.

I'm pretty sure the Dougs headers are almost identical to the TTI's....and fit just as well. For a build like yours a 1 7/8in primary tube header is the right choice. A 2in primary will kill of some torque and low end power.  ;)

Thank you.

@Ron: it's a 440 stroker with 505cui.
I bought that motor from Todd (Competition Wedge Engines). Compression ratio is 10. 5. It's got a Comp Cams hydraulic roller cam, duration @ .050" 230 intake, 236 exhaust. Would it be better to use 2" primary tubes in this case?

I think Doug's headers are cheaper by $200 than the comparable TTi, if that means anything to you...

With a 500in build....torque is no problemo !  :icon_smile_big:

In that case the 2in primary tube headers are fine. If the Doug's are less expensive then that's the way to go. I've seen both and the quality is the same. I wouldn't have a problem with the Doug's on my car even though I have the TTI's on it now  ;)

Todd builds a nice engine....I'm sure you'll be very happy with it  :2thumbs:

I bought my short block 512 and Indy heads done by Todd . Ron is right , you won`t be disappointed . I went with the Tti headers on mine . :2thumbs:

Thank you very much for all these informations.
So, I will go for Doug´s headers.

Did they have a coating on them?  We're they plain?

I have Doug's on my 440, they are ceramic chrome coated. Pretty blue looking close to the intake and a bit of surface rust down the seam line to the collector, but other wise fine, they've probably been on this car at least 14 years, I should add I've done 10,000 miles on them

Thanks for the input.  Your post just made Dougs a real contender as a choice of headers for me...

SO I was putting funds aside to replace my hookers with TTI because its  pain changing angled plugs

how does the headers from dougs work with angled plug heads?

I love their cutouts and would by their headers if they fit as well as tti

scott1973

I like this thread since I am in the market for a set of headers as well.  Going on a 470" stroker.  I was under the impression that only the TTI's would fit with the angled spark plugs on the Edelbrock heads which I have as well.  I have three concerns with the TTI's. 
1.  It says to use an old set of headers or manifolds for the break in.  Is this necessary?  I have Hooker Comps and they wont fit and a set of HP manifolds which I have not tried. 
2.  It states that we need to shorten one of the transmission linkage brackets.  Does not look to complicated but its just one more thing to do.  Do the Dougs headers fit with angled plugs? 
3.  Which starter to use?  I bought a mini starter from 440 Source and figured it would work with just about anything.

Do the Dougs headers have these same issues? 

Thanks for any help,
Scott

scott1973

Nevermind.  I answered my own questions.  I see Dougs does not offer headers for a 73 Charger so that eliminates them.  TTI has a list of starters that will fit on their site so that answers that question.  Looks like TTI it is.  Hope I dont destroy the ceramic coating getting it started for the first time and breaking it in.   

Thanks,
Scott

Mini starter was already installed when I got it.
I'll put up some pics tonight of the plugs and discolouration

Ok, there we go, traces of QQ1... :lol:
Passenger side is hitting the shock tower when I really lean on it
The oil cap sometimes pukes onto the header after a big rev which is why it is discoloured there

Driver side almost drops in, right? :2thumbs:  The passenger side was the challenge on mine, car clear up in the air, header fed in from below with a helper moving the engine from the top side...   Good comment on the shock tower, mine was clear when I first installed the headers and the same tube has 'self clearanced', like yours.  I'd tweek the header first if it was going into a nice new engine bay but the tower did a nice job in my ratty car.

One tube is also pretty close to the torsion bar on the passenger side but hasn't hit, and on the driver side there is good clearance around the mini starter and bell housing.  I did use a braided plug wire sleeves to keep the heat off the cables going to the starter and spark plug boots and in 3 years have not had a heat soak issue, either.

Sleeves similar to these:

Can't argue with that one.  There many reasons why not to go that route...

Probably if I had a torque bar opposing the motor travel it would alleviate the fouling on the shock tower.
The braids are a good idea, I just wrapped mine with glass sleeving tape and wired it in place.

Yes, close to the torsion bars in one place, I have some more pics on another PC, will have a look tonight

Ok so it looks that the extra 150 ish is still worth it when running with angled plugs

I ordered Doug's D452's for my 440.
They did not fit like supposed. I had to massage them at the steering gearbox and also on the passenger side torsion bar..
I was able to get them in from underneath the car. On the passenger side it is easy.
On the drivers side I had to remove the steering linkage on the pitman arm,
the torsion bar and had to raise the engine at the rearend about 1 or two inches.
