Remember, the head is CAST IRON and reall, really heavy. I would make sure you have an engine lift or powerful hoist in place FIRST. Trying to do this job alone (without lift etc.), you WILL hurt yourself and possibly damage your head/ block/engine compartment/accessories. I must stress this. It took two people to remove the small (in comparison) alluminum head from my BMW project car. Weighed 90lbs. Very difficult to lift and position while leaning over engine compartment. I wouldn't dream of dooing your job without a crane!

Otherwise good luck and work safely.
