Default EJ20 and its options.

I have an 02 wrx so my current block is ej205 i'm thinking.. my questions is are all ej20 blocks interchangeable? such as an ej207 block with my USDM heads? I'm just looking to do a simple plug and play.. not looking to modify

Ej207 is plug and play with your car. So is an Ej257 block, with the proper head gasket. In general it's better to stay away from any of the older Ej20G, Ej20K and twin turbo Ej20H or Ej20R blocks. They tend to bump your compression ratio a bit more than you want and often require thicker early JDM head gaskets for piston clearance.
