Technical Headers from Jamco made by advance adapters inc.

I`m doing an engine swap in my 51 shoebox and I bought some headers from Jamco made by Advanced adapters Inc. and I took a look on how they were made. I`m not happy,they look OK on the outside but on the inside they are not so great. Here are some pics. If you buy a set inspect them well if you want the best performance out of your engine. The tubing sticks out past the welds into the big tube when i think they should be flush with the inside of the big tube. Since it took a while to get them I`m mulling what to do fix them myself or returning the headers.

Ever watch the dyno video the Frieburger did on headers when he beat them up? File or grind the dingle berries if you want but I’ll never worry about hammering a dent to clear something again for sure…

 

On a street car you'll never see any difference...

 

Hello Jimmy
I haven`t seen the video please post a link.. If I have to dent mine to clear something and can`t get around it I will but this are not dingle berries one of the tubes blocks half the exhaust pathway and I don`t think that helps performance.
Juan

 

Get a hole saw that fits inside the tubing, use a drill extension and cut it out.

 

I would send them back and demand my money returned.

 

Header bash fest conclusion, it does nothing.

Like he^^^said!
Maybe you still get what you pay for.?! (Like the Patriot Headers I bought! Beat to fit should be there motto. Hard to install. Burn plug wires. That about covers it. Shoulda bought ****** I guess)

It seems like there's complaints about Jamco fairly regularly. But remember this; they're about the only company that offers certain specific parts for some cars, particularly the '49-51 Fords, so if you don't like what they have you'll be on your own. They also try to keep prices low, so expecting top-drawer quality can be a bit much.

 

Those are anti reversion tubes. Prevents g***es from flowing backwards during valve closing.

 

They look like Helen Keller welded them......I would not accept that poor quality. And for a street car, just find some good stock manifolds, less headache

 

I've used a set of those from jamco also but the tubes on the one I got only came into the main pipe about a quarter inch. I'd call him up and tell him what's happening I'm sure they would do something about it

 

Those might work fine but they sure look like hell. Considering the gorgeous set of headers I bought dirt cheap off of Amazon, I'd say their QC has some real work to do.

 

Have you talked to Jamco directly about your concerns?

 

Always should be step one....

 

Hello
You guys are right I should have contacted Jamco first is just that I`m upset about this QC problem.
Juan

 

Be nice to them. They are a reseller of Advanced Adapters parts. They did not make these.

The QC issue would be with AA, unless you'd have Jamco open and inspect every single thing that they do not make, but sell, before you get it.

I am not sure that they could charge enough to cover the extra staff to do this.

 

Does ****** or Hedman make headers for your application? If it were me, I'd box 'em up and return them, pronto! That's unacceptable! Buy some quality headers.
I bought a set of cheapo Ebay headers and they were complete junk. Sent 'em back and bought a set of Hedmans which I'm very happy with! You get what you pay for!

 

The choices for headers that go on an small-block Chevy, in a shoebox Ford ch***is, is somewhat limited.

These will work fine, once the obstructed path has been cleared. Someone messed up. It happens.

 

Just "baffling"

 

I spent a few years building headers and workmanship like that is totally unacceptable. Take ‘em back, be nice and get your money back.

 

No bueno .

 

I just installed a SS set of header's on an off topic, typical mid 90's truck 350 cracked cast iron manifolds, I couldn't buy doorman replacement's for the $102.00 delivered to my door..
Tig welded, Polished, exact fit to Y pipe..
Since it looks SBC, You have Way to many options for that ****ery..

 

You can also get long carbide grinding burrs, mite work if you wanted to spend the time

 

since the outlet pipe is straight, you could just cut it off near where the offending tube is attached, and then you could get to it more easily to cut that part out.

And thanks for the warning about the headers. Looks like they cost several hundred bucks....I agree you should have got a better product for your $$$.

 

There are HAMB threads with concerns about JAMCO going back a decade or more. But,times change as does management and I'd at least try to give them a chance to fix your problem. It may be true that they can't examine everything that they resell, but they are the ones responsible for selling it to you and it's their rep on the line.

 

Those JAMCO headers are incorrectly and poorly made.. Send them back. Here's an interesting article and videos on "anti-reversion" as it relates to exhaust and engine performance.
It seems that anti-reversion would work better using the anti reversion tubes at the "collector end" of the exhaust header pipe instead of making obstructive headers like JAMCO produces.

Hello Guys
I have contacted Jamco about the headers and I received a prompt reply from Anthony at Jamco. Like I wrote at the beginning these are made by an outside vendor called Advanced Adapters Inc. His reply is as follows:

Hello Juan
I received pictures and will forward them to my manufacturer. They should be able to send replacement. I am sorry for the problem I will give you a time frame on the replacements after I speak to vendor.

Thanks
I will be waiting for the replacements and will let you guys know how things turn out..
Juan

 

But.... Jamco is the en***y that collected his $$ and profited by it. It IS up to them to ensure the quality of products they sell. P***ing the problem back to AA is Jamco's responsibility, and they need to know that THEIR customers are upset. That's part of the problem we face in today's world, suppliers don't want to accept responsibility for the products they sell, whether they manufacture them or not. In my opinion and a lifetime of work/business experience, every part I sell is my responsibility, no ifs, ands or buts. It's Jamco's sales reputation on the line. they should take an active role in making it right!

 

As the OP mentioned, he did not contact Jamco first, so they have not to our knowledge been made aware of this.

Also, we don't know if Jamco even had these in their possession to inspect. For an item this large, from a third-party, they may well have been drop-shipped, making it impossible for them to inspect anything. For all anyone knows, every sample they did inspect has been fine, and this is the first issue.

The problem here is that folks, including you, are ***uming the worst, and the OP did not notify Jamco, first.

The only way that Jamco's reputation would be on the line here is that there is now a thread on the internet of people blowing up an issue that they don't know about. That is a dangerous game to play with a business reputation.

And, as has been clearly stated in the post before yours, the instant that they were notified, they took action to take care of it.
