I just did headers last week........drop the k member........trust me.
I was able to get the passenger header 8n with the kmember in place, but the drivers side is so tight and you will have so much issues trying to get the drivers side motor mount.
I was nervous dropping the k member but it is quite simple and tons of room to do the headers.
Drop the k......
I agree. Drop the K I tried to do it at first without dropping and the time I spent screwing with it I could have had the K down and out of the way.
