Hello everyone. Been having some issues lately and found the cause. One of my valve retainers wasn't seated and since I have installed a new head gasket plus a bunch of other things I'm trying to figure out a way to get those pesky retainers back on while keeping the head bolted to the jug. Yes I am aware that there is such a tool for this once the head is removed but I'm hoping someone else has accomplished this difficult task without removing the head. Thanks in advance.
