I used the 6/sb k member. Had to remove most of the motor mount on dr side to clear oil pump. Used an engine plate as well. I also used 1 schumacher conversion motor mount on pass side only to fully anchor engine to prevern fore and aft movement. I also used Maddog headers which go in 1 tube at a time. That made things a little easier.
I would call them. Easiest headers i ever installed. About 10 minutes pass side. Dr side was a little more involved and required a couple dings and shorten steering column tube. I would buy them again.
