Hey nice products guys,
Im interested in the ls1 1.9 ratio rockers, but im also looking at adding a cam. If a cam is designed for high ratio rockers, will they be ok to use. The cam is Comp cams XR273HR, it only has a max lift of .53/.534, and states it likes high ratio rockers. I have calculated the max lift after the 1.9 rockers are fitted is .594. ill be adding pac performance valve springs which are rated to .625 lift. Any advice?
