from DDG: "There are 6 cam sprockets for the SOHC 2.2/2.5 family

1984-1988 "4201974" Square tooth 2.2 Turbo, 2.2 N/A
1984-1987 "4201992" Square tooth hi-output 2.2 N/A
1989-1992 "4387557" Round tooth 2.2/2.5 Turbo, 2.2 N/A
1989-1993 "4448690" Round tooth 2.5 N/A "common block"
1986-1987 "4273238" Square tooth, "tall deck" 2.5 TBI ONLY
1988 ......... "4387535" Round tooth, "tall deck" 2.5 TBI ONLY "

if you consider a TURBO cam "straight up",
then both the 4201992 and the 4448690 will provide 4 degrees of 'retard'

I've never seen the 'tall-deck' gears .. dunno what is special about them ?
