You'll probably have to trim the baffles to get clearance, depending upon the particular rockers you got.
The Pro Comp stainless steel roller rockers from Comp Cams are about the only ones that clear without problems.

Re: 1.5 rr under perm covers??
They'll clear under just about any aftermarket covers though. I'm running the standard height Edelbrock Elite Series perimeter bolt covers with the bulky Harland Sharp, aluminum, 1.5 rr's w/poly locks, and they clear just fine. Most cast aluminum covers just use a small tin plate with two rivets or screws as a baffle, so they don't interfere at all. It's the stamped steel ones with the large baffle assembly that have clearance issues.
