I believe the Covellos from the Grand Ave crew were involved in the Messino's drug operation. I was reading an article from 1987-1988 when the drug busts all went down.
I'm not too familiar with the Chicago Heights crew besides what's been written about them. A friend of mine had some dealings with them back in the 70's but it was mostly drug related. He dealt with Sam Annerino and some of his guys.
