Vortec Header Questions?

[72longbed]

Here's one that I need some help on please,
I have a Vortec head engine in my 72 K20. I'm running Hedman #69238 hedders. The exhaust ports do not match my cylinder heads ... restricted by over a 1/4 inch on the "width" of each exhaust port. The height of each port is good. I think there is a solution here, and it may be that there is a manufacturer that makes a 'Vortec' header for our trucks?

Does anybody have experience with this situation, or know of a header that matches Vortec ports AND fits our trucks?

Thanks for your help.
