What special rules are you talking about, the deathcompany and how they are generated prior to battle and the unit changes / additions or the general space marine rules such as "And They Shall Know No Fear"
Just show him the Blood Angel Codex. Unless you don't have one--then you can pick up a copy at your nearest games dealer for like $10. Or you might even be able to get a copy off eBay for like $5 or $6. But you gotta use the codex--we can't post special rules or stats on the boards that you'd find by looking in the codex, k? Hope this helps.
