Just inquiring about Mace's 1.9.1 ratio rockers,stage 2 cam and memcal package for VS getrag do these two products work in conjunction with each other?

Assuming you're referring to our COMP Cam and tune package, then we would not recommend a set of 1.9:1 ratio rockers with this cam as it would cause engine damage. If you're referring to the CROW Cam and tune package to suit an ecotec then it will be fine provided you use 130# valve springs, our shorter retainers, our valve stem seals and a double row timing chain set.
