I am looking at new rockers, already have stage 2 cam and chip from Mace plus pacemakers lukey exhaust SS growler kit and upgraded valve springs just want to know what would be the best option for rockers to put in as looking to see some good gains after

It depends on the cam you currently have. For instance, if you have one of our Stage 1 or 2 CROW cam packages to suit an ecotec, then a set of our 1.9:1 ratio rockers in conjunction with suitable valve springs, retainers would work well For all other cam combinations, unless you were planning on doing some cylinder head work (port, machine head for extra compression, machine down valve guides), upgrade valve springs to accommodate for the extra lift and get a custom tune done, the I wouldn't worry about going a set of higher ratio ratio rockers
