My '84 pickup came with an extra core engine. I'm wondering how to positively identify whether it is a 22R or a 20R? I'd expect there would be casting numbers somewhere on the outside that would positively identify it, or some other distinguishing characteristics?

Are the cylinder heads interchangeable between 20R and 22R?

The 20R also has larger ports that will give you more power.
