Hey guys. I figured I would ask here before buying anywhere else. I need a set of valve spring for my j-heads. The cam im running is a MP PS .528 solid. 1.5 rockers, stock valves, installed height is around 1.875", my retainer OD is 1.350", the guide boss OD is .750". I'd like to stay around 1.4" OD on the springs for rocker clearance. Thanks guys!
