Motor Install with Lift Plate on Intake?

Are those 4 - 5/16 bolts holding the plate to the intake really able to suspend a load like an engine/trans combo for as long as you need without issue, its got to be 600lbs ish. I'm thinking it could be suspened for 4-6 hours while installing. If the intake was steel I wouldn't worry as much, but lifting like that on my aluminum Indy intake makes me wonder. Am I silly for being concerned?
