Recommendations for good "A" street header

Captainkirk said
Soon (hopefully when the weather breaks in the spring) I will be shopping for a new set of headers for my A-body '72 340 Duster. The car has power brakes but manual steering, and a 4 speed for fitment. J-heads. Looking for recommendations on a decent set of street headers that will fit with no body modifications and won't break the bank, from you guys that have actually installed them and had a chance to evaluate the ease of installation and performance gains, as well as durability and quality. FWIW, the engine is out of the car (resto) so going in might be a little easier than some installs.
I don't mind spending a little extra if it's gonna actually buy me something.
Talk to me.

Dougs D453’s. I run them on my ‘74 Duster. 340, manual steering, previously a 4 speed, now with a T56.

The Doug’s are tucked in closer than the TTI long tubes by about 3/8”. You’ll need the same modifications to the z-bar for both the Doug’s and the TTI headers. And the mini-starter for both as well. With the mini starter you can do a starter swap without removing anything else, just have to turn the steering all the way to the right.

I bought a set of TTI shorties to gain some additional ground clearance from the Doug’s, after installing them I switched back to the Doug’s. Finish on the Doug’s was better. And even the TTI shorties has just as many tight spots as the Doug’s. I compared those two in my install here My "new" '74 Duster- or why I need a project like a hole in the head

I did have to dimple the D453’s at the torsion bars on both sides. But it was a very small dimple and I run 1.12” torsion bars. Plus with the spool mount K there’s really no way to adjust the engine. With the biscuit mounts you can shim them a little to make adjustments. I’d buy the D453’s every time for a small block a-body.

Interesting...Summit says the D453 headers do NOT fit my 1973 Duster.

They do, the stupid fitment chart has been wrong for years. I have them on my ‘74.

Do any of these longtubes fit cars with power steering? I'm thinking about doing some on my 71 Dart.

The Doug’s D453’s will. So will the TTI’s. Some of the cheaper ones will too, but some of those won’t too.
