Some do, some don't. The SC motors, that I know of, never did, but I believe they had lower compression, as well.
3.4's sometimes knock a bit as well on 87 octane, the fix is to spray warmed water from a spray bottle into the intake for about 5 minutes after it's warm. You'll see the carbon crap come out the exhaust.
