You may be able to move the mounts a little, or even widen the slots in the mounts on the K to shift the engine over.
I didn't have any options at all, as my Doug's headers are also right up against the inner fender on the passenger side. Moving the engine would have made my fit even worse on the passenger side. Sorry. Not all of these cars, or all of those headers, are identical. Some things fit one car far better than they do another, just depends on how yours rolled off the line.
