Any advice on my 188 engine swap in the old ck would be appreciated

Stopped running her immediately and after several years of looking I found a replacement engine.Wondering what i should replace on the “new to me “ engine before installing it. Rear main seal? Other gaskets ?...?? Or just install it as is ?? Also should I replace and seals like the converter seal? ( I have a power shuttle unit ) Any help and tips would be...
