on the drivers side of the block, there is an identifier in the casting. "FE" is a 2 liter, "F2" is a 2.2.
Also, the 2 liter was only available for two years, 86-87. The 2.2 was available from 86-93.
Additionally, the 2 liter upper timing cover is smooth with a bump at where the center of the cam gear would be, the 2.2 upper cover is ribbed vertically.
If you pull the valve cover, the rockers are manually adjusted on the 2.0, hydraulic ( and no adjusters) on the 2.2.
And one more, the lower timing covers are usually marked 2.0 or 2.2.
There are always exceptions, people change out parts all the time like cam covers and heads (they interchange between 2.0 and 2.2). For example, my engine has a ribbed upper timing cover and hydraulic rockers, but its a Japanese market 2.0.
