As promised here is the review of my Doug’s headers install. First let me start by saying these headers are absolutely amazing! These are Doug's D453 ceramic coated small block headers, installed in my 72 Dodge Challenger with a 340 and 727 torqueflite. As you can see in the comparison pictures (old headers are cheap Dynomax headers) the Doug’s headers have cleaner, tighter bends and the collectors are closer to the body. One of the real nice benefits I have discovered about the Doug’s headers compared to the Dynomax headers is that the new denso mini starter can be installed and removed without loosening the header, which is really nice. To remove the old headers I had to remove the oil filter and 90 degree adaptor, and drop down the steering components. Also during my install I converted from manual to power steering, so I had a lot of room to work, and it didn’t take that much time to remove those components. My wife was kind enough to tape the Doug’s headers so I wouldn’t scratch the ceramic coating during the install. The installation instructions called for jacking up the engine, which may not have been necessary, but it definitely made it easy. Both headers went right in. I have never had a set of headers that went in this easy and have so much clearance around everything. As you can see by the pictures there is tons of room around everything, the power steering box, the spark plug wires, the steering shaft, even the ground. Also with the way the tubes come out of flange there is plenty of room to install and room all of the header bolts. The install took pretty much all day, but I was taking my time and took several breaks throughout the day. Enjoy the pictures and if you have any questions feel free to ask. Oh yeah and here are a couple videos I made during the install of my car uncorked.
Mods, would consider making this a sticky for the header install? I know a lot of people have had a lot of questions on headers for e bodies and this can at least answer those questions for the Doug's headers.
