340 head gasket leaking with sleeves

Did the sleeves move at all or werected they never decked properly from the get go. I find it odd that all 8 were sleeved. I was always told if you were putting more than 2 sleeves in the same bank it was time for a new block. I find it hard to believe that a press fit sleeve worked it's way up against the pressing force of the head gasket. I have worked on 8.0 Viper motors which have replaceable wet sleeves. We use a special tool to hold the sleeves in when the head is off and it is removed when we install the heads.
I would recommend trying to drive the sleeve back down. If they goes down easily either replace them with a thicker wall sleeve or new block. If they don't budge and are bottomed out I might just try decking the block to even it up. May have been improper decking by previous machinist..
