Aj16 engine removal

I just managed to remove the engine from a project car , has anyone ever worked on an aj16 engine , i am getting rid of this engine as it has thrown a rod , i have a chevy engine ( just kidding) , a good used aj16 engine to use .
what would be a good place to work on the engine and replace any gaskets and seals that are easy to have access .
should i use an engine stand engine dolly or heavy duty table , i will need to have access to rear main seal ,

are the flexplate bolts regular 12 point bolts or they require a special socket
