Jeggs Headers?

incinr8 · Jul 9, 2018

Anyone use Jeggs Headers on a 69 Roadrunner 383? I searched with no results.
I"m looking at these, About half the Price as others and probably half the quality? Thoughts?

I have them on my 69 GTX 440. They need clearanced around the torsion bars on both sides. Spark plug access on my Stealth heads is very good.

I guess it depends on how long you are going to keep your car. There is a reason that they are less cost.
1) 18 ga. steel tubes verses 16 ga. on Dougs or TTI
2) 5/16" thick flanges verses 3/8" flanges
If clearance to the torsion bars is a problem, my experience has been that new motor mounts can help. Worst case, there are shims available to raise the engine up 1/4" or so.
The Model D452 Dougs header did not require any "modifications" to fit my car.

Has the OP considered Summit/Flow Tech brand?

Around $400 ceramic coated, sometimes on sale as low as $333.

The D452's I just put on mine had one of the primary tubes just kiss the passenger side torsion bar forcing me to ding it to clear it. No big deal but it is a tight squeeze.

Talking about "dinging" header tubes always brings a smile to my face after watching the Road Kill episode where Frieberger beat the crap out of the header tubes on a dyno motor with virtually no change in the horsepower or torque output...

I think I saw a youtube clip of that. No cable out here in God's country, so I miss most of these shows.

Dinging mine up didn't make me lose sleep but the ceramic coating was damaged around it. If they were made tucked toward the motor an inch they would fit perfect. I would like to replace them in the future with 2" headers but no need as they work just fine.

If they need to be moved together for more tb clearance, I just wrap a ratchet strap around the collector and squeeze. I also used a floor jack under the collector of my old hookers to get them closer to the floor.
