You either need to buy rockers direct from GM, or get a new set of studs (3/8 or 7/16) with a new set of rockers. I don't know of any aftermarket 10mm rockers that will work properly

update:zix you are correct.gm has the rockers still.but at $66 a piece i think not.the parts guy graciously lowered it to $50 a piece.so not having a money tree in the backyard i opted to buy new studs and run comp roller tip rockers in the factory 1.6 ratio.not a full roller but on a street motor i dont expect to lose much if any.what a headache!
