Thanks JB.
Taking things apart was done in spare time. I couldn't remember what all needed removed, and in what order. I probably spent 3 or 4 hrs getting it out.
It went back together in 2hrs though. That's from complete passenger side disassembly to fully assembled and of the jacks, ready to drive.

Well guys, I took my weekend trip down to Pigeon Forge this weekend and all went well.
There's probably 12 hrs of driving at 80-90mph (2800rpm - 3200rpm) and 8 drag-strip passes. (1/8th mile)
I did 3 passes back to back........let her cool for a hour, then did another 3 passes back to back, then let her cool down again,...then did another two back to back.
No issues with the new welding so far. Time will tell!

BA, glad to hear the weld repair is holding up.
For me it appears that I do, in fact, have a crack in the passenger side header collector weldment.
It's not a big crack like yours, but it probably will propagate ( grow ) with time and cycles. I'll be talking to Loren at S&S tomorrow to get a replacement passenger side header. Oh boy, more fun taking out the cracked header and installing the new one.
Well at least I've been there, done that before, so like you it should go somewhat quicker.

Not trying to be skeptical, but, you saw my pics, and we both know that I didn't do anything to "force" the crack to appear, but I'd bet a months pay that (as you said) your crack will just grow over time, especially as the header has intense heat cycles and engine torquing.
That's a bummer to hear. You know I feel your pain bro.
Do yourself a favor and don't install a replacement that hasn't been rewelded in some fashion or else you know it will just come back.
Good luck man.

I'm sure it will grow, too. I'm waiting to talk to Loren and I will see about getting that area reinforced. I'll probably use your pics for examples. It will be worth it to wait a few more days and get this done right so I don't have to un-install/re-install again
Hard to hear my normally great sounding V8 'burble' along with the header leak. At least when I have the windows up and the AC on I don't really hear it, so that makes it bearable, but still embarrasing.

Well Loren sent me a replacement passenger side header ( received today ) and it appears that this one does have more weld between the front two runners - not as much as BA's repair, but certainly more than what BA's or my original header had. Now I get to have all that fun again, taking out the cracked header and installing the new one - at least it's the passenger side ( the easier of the two sides ).
Now I'm just trying to decide if I will do it tonight -or- wait until Saturday. Probably Saturday.

On a side note, glad to hear you got your new header!

Well, I decided not to wait - did the install last night ( a late night! ).
Now I remember what a PITA the job is doing it on jackstands in the garage.
The passenger side header had two cracks in the same area that BA's passenger side did. One was very small and relatively tight and the other was in between the runners. It appears that lack of penetration is a primary driver with the cracking. The cracks were very close to each other - I'll post some pics Saturday.
My replacement passenger side header had good penetration and more weld in the area of concern. I also had the header inspected by fluorescent penetrant at my place of work yesterday before installing. No cracks were found
I'm glad to have my nice V8 rumble back without the 'burble' sound of an exhaust leak.

Are you busy next weekend? I want to come by so that you can install mine.
I'll treat you to a nice dinner afterwards.

You slay me Teelex:
"I also had the header inspected by fluorescent penetrant at my place of work yesterday before installing"
and I thought the boroscope was cool, now you come up with this! :-D I'm jealous!
Glad you got it all wrapped up, AND you even got a replacement pipe out of S&S which is more than I can say.
Got any pictures of the pipe that they sent to you?? I was hoping to see their fix!
