No, a roller rocker and a solid rocker cannot interchange on a 4.3 Vortec Chevy without modifications. The two types of rockers are designed for different valve train systems and may have different geometries, which can affect performance and clearance. Additionally, using incompatible rockers can lead to improper valve timing and potential engine damage. Always check compatibility and specifications before making any changes.
