Why are you avoiding the recomended header?
The exhaust ports are raised ports the alignment should be the same . Tech said the factory non rams definitely interfere with the plugs .

I really don’t like headers on fairly stock motors no need for them and there’s always figment issues and the rust fairly quick . I have ceramic headman headers on my Chevelle after 3 or seasons they look like crap .
