Your absolutely right. I had to make a 1/4" plate anvil the width of the tube ID, with rounded corners, that I clamped into the vice. On my header flanges the perimeter of the port is equal to the OD circumference of the 1.75" primary tubes, so that when formed the tubes slide into the flange. Not sure if yours are that way or not. With the SBF ports being taller than they are wide the tool you made would be a bit more "interesting" to form.

This little tool was originally made for SBF headers, just use the first few inches of it.

Steve, if the tool is square how did you deal with the rectangular ports on SBF headers? Wingnuts look killer, BTW!

When you do the long side you just move it side to side.
