I don't think its the rockers that really need the heavier oil... its the dealer recommending it so that drivers who get this modification don't complain about the "sewing machine" sound.
I still say if you WANT to go to a heavier oil a "thick 30" ("German" Castrol) or "thin 40" (M1 0w40) would be just the ticket.
If you don't care about a little more harmless noise, use the stock grade in your favorite brand and don't worry about it.
