quick questions, visually how would you tell the difference between jdm k20 found in the ep3 and k20a2 in the dc5r?

besides block number etc.
anything else that would give it away and tell the difference?
i did a quick searched on vicroads vehicle check and
engine number: k20a2242xxxx , possible vicroads got it wrong? or engine was swapped over?

car is a far way from my area to go see, dont want to get there and not know what im looking for to distinguish between the two.

cheers in advance
