Best 318 headers

Hey guys. First post here, came over from the Dodge Charger forum. They treat 318's like grocery getters over there so hoping to find more help here.

My 318 is about to come out of my 73 Charger. Rear main seal, new cam, and some other upgrades coming. Will ask for advise in the proper threads for those upgrades.
While it's out I'm thinking about some headers. The car has dual exhaust now but straight back pipes coming off the old cast iron original logs. Don't know if I should replace a section of pipe and put in an H pipe or if the straight pipes are fine. Who has had luck with what headers in a 318? I've already installed a mini starter so hopefully won't have any clearance issues if I choose the correct headers.

Thanks
Alan
