Magnum Roller Lifters
You may be able to get small block Chevy rockers cheaper. Not saying cheap is good, but if you can get higher quality rockers for SBC cheaper....why not? I know several people who have used the SBC roller rockers on Magnum heads with good results. Maybe do a little research on the SBC rocker swap before plunking down mo money. Hopefully, the pieces of that busted rocker that are MIA got by the cam without causing any damage.
