Got the Speedway headers in today.

First thing I noticed was the flanges were only about 1/8" thick. And, when they say they are block huggers, they aren't kidding. The collector looks like it was touching the block the same time the flanges were seated on the exhaust ports. I was afraid once they were bolted down, there might be some stress if they were bending the tubes.

But, I didn't have to worry about finding out if they were going to be stressed. I didn't get that far.

The #3 tube was about 1/16" away from the spark plug!

Since they are ceramic, I figured dimpling the tube wasn't the answer, so I packed them up to send back.

How hard could it have been to move the tube just a little in the design? I guess I got what I paid for.
