Cable shifter issue, please help!

Please help! If this post shouldn't be here I apologize, I just figured there would be more likelihood of someone having this setup here.

I just dropped a fresh 360 in my 68 valiant with a set of Doug's Headers and I am playing hell finding a good route for my shifter cable that doesn't want to lay on the headers. With the 5.2 magnum I took out of the car and the cheap hedman type headers I didn't have near as much issue with this.

Is there anyone who has put a LA small block with Doug's Headers and a cable shifter that can provide some guidance.

Thank you in advance
