Mopar Cam 284/484 or 288/497

Well thanks for all your info. Will be getting cam offset keys from Mazzolini parts. Also already have a true roller cloyes (the better one not street roller). Although engine has roughly 65 to 70000 miles since rebuild may need new chain set. Is rollmaster or JP timing set any better? Theres all kinds of claims to be the best. IWIS german chain?
