steve, mike,

it's not that someone cleaned up the clearance issues. check it; there are two major manufacturers of the tri-y header. one is foreign and one is american. sadly, i forget which way this goes. one of them is a near-to-spec reproduction of the dead-on-spec original style tri-y. you can tell the difference because on the driver's side of the car the correct ones will miss the steering arm on all but power steering equipped cars. i'm assuming your ceramic coated tri y headers are the correct original spec headers, since i personally wouldn't spend the money on ceramic headers that didn't fit right and required extra bends and dents.

so essentially, it's the same deal as the OEM exact repro vs. aftermarket repro fender issue: the curve just doesn't quite fit right on the cheaper part. this isn't likely to change any time soon anyway.

Dan,

I picked mine up at Mustangs Unlimited in the early 80's and have no idea who made them. Mustangs Unlimited went down a path of selling low quality made in China parts back then, so who knows where the headers came from. They came painted black and I had them alumicoated for $75.00 which has held up extremely well.

I haven't had any of the above troubles with my tri-y's. No issues with removing spark plugs or with clearance to the steering linkage. The only close area is with the clutch z-bar, but as long as it floats on the bushings it is not a problem. I guess they're not all created equal. I used Doug's Headers, ceramic coated. Pricey, but it sounds like I avoided a couple of issues.

I forgot to mention, I've had mine on the car for about 20 years. Sounds like somebody cleaned up the clearance issues. <img src=images/icon_smile.gif border=0 align=middle>

I have the same problems with my Tri-Ys. The other thing to look out for is where the steel plate bolts to the head. There are a couple tight spots for getting a socket on the spark plugs. The solution was to mark the spots and then remove the header and start grinding metal. As I recall, it was maybe 3 plugs that needed more clearance and about 30 minutes with a grinding stone took care of the problem. Then it was off to have the headers coated.
