Header Install Question - 440 68 Barracuda

I put in Schumachers with my 440 about 6 months ago or so. They go in from the top. Pull the plugs. Unbolt the motor mounts from the k-frame and jack the engine up as far as it will go, several inches. I believe the starter can stay installed. The dipstick will get in the way a little bit but mine stayed in place. They really go in pretty easy.
Good luck
