The head on my 1992 300SE was extremely heavy. I wish I had weighed it but i would estimate close to 100lbs. or more. I did manage to pull it off by myself when doing a valve job recently, but it was very difficult. Have someone help you to prevent injury or damage.


When replacing the head I would recommend using an engine hoist to lower it and to avoid damaging the head gasket. Extreme care is necessary when lowering into place. An extra person or two would be wise.

A tip - put the rear four head bolts into the head before lowering. These are difficult to impossible to put in after the head is in place. It's a big job but having done it successfully it feels really good.
