hooker fenderwell headers

I'm in the process of mocking up a 440 in a 70 Duster. I have 2" Hooker fenderwell headers. using Schumacher mounts with a 6 cyl k frame. Pass side collector is too high. Trans crossmember will need to be tunneled for pipe. Eng is level. Anybody have issues with these headers.? Pn-5215. Driver side is ok.
