I run the Trick Flow Rockers. They are CONSIDERABLY smaller than many of the RRs out there but you'll still have to trim and grind down the baffle on the stock covers to make them fit. Either that, or you'll have to run a pretty thick gasket.
I put the Canton Racing ones on and I think they are B E A Utiful, but if ya gotta run stockers then the advice herein has been sufficient. You may need to trim the baffle...
