Roller Rockers ???
Depends on the cam you run. I have Comp Pro Magnum rockers on my Eddy headed 410 stroker, but If you have a solid roller with spring pressures over 500#'s you should either get them bushed, or get another rocker. I think the newer version of the Pro Magnum rocker is bushed...but I'm not sure (might want to check into that if interested).
I have also tried (just last week) to put some Harland Sharp 1.6 rockers on my Eddy's. The sweep was spot on, but the rockers didn't clear my 1.54" diameter springs...which stinks because Summit says they will clear 1.56" springs...oh well, I'm sending them back because I don't feel like grinding on brand new 600+ dollar rockers. I have also heard good things about the rockers from Hughes Engines, but I have no experience with them.
