Default Exhaust order for 7/4 swap cam

I'm running a 7/4 swap cam does anyone know FOR SURE the order in which the exhaust pipes should be paired. I think it's 1 3 5 7 , 2 6 4 8. Please let me know if this is right or wrong. I already have my headers made from lemons but I will change them if I have too. Thanks for looking.

I guess I am not sure what you are asking...How are you going to pair exhaust pipe 2 and 6 (or 4 and 8) Do you mean at the collector? :?:

I can't see any difference for the exhaust unless you were building 180 degree headers, not likely, or 4-2-1 headers. I run the same ones on my dragster, 4 to 1, with the 4/7 as I did with the standard cams.

Only makes a difference if using tri-y headers and then they are different for the 4-7 firing order swap
