It could be a 2.0 or it could be a 2.2 with a 2.0 head. The part your talking about is the part the distributor goes in. If so that you can use the 2.0 part on a 2.2 block. but not the other way around. the 2.0 one is a little shorter than the 2.2 that's why it can be used on the 2.2 block. there is a casting on the block some were but not sure were.
