do not do this, carrying cylinder head off Cummins 220 not big but heavy, could not quite get it on the bench so had to lift a bit higher and right up to the metal bench ,angle iron edge , get the picture ,men's bits now on bench because had to reach up and tight up to the bench ,( stop laughing) then put cylinder head down rather heavy .You do not have to guess much to no the outcome ,STOP LAUGHING.
