Header fitment rant, Doug's

I will never buy another under the steering header, even if someone gives me a set.
I installed TTIs on my Eddie-headed and decked 360, and yes I had to make a few BFH adjustments. That is called making it work, and HotRodding. I mean everything on my car got there because I made it work. The headers were the least of my problems.
The thing is, those TTIs are still on the car 20 years later. Yeah the merges leak a lil, again. Nothing I can't fix. How many under the steering headers, can boast a 20 year and counting, lifespan?
Oh and I almost forgot; the header gaskets on these have never leaked and the bolts have never come loose.
