Default Header Measurement Needed

Thought I should have posted this here rather than the street section...


Anyone with round port Doug's headers on a 64-67 GTO that can tell me what the center to center is on the collectors?

I have D port Doug's and I may be switching to round port heads. Wondering if it will line up to my X pipe.

Thanks
