[quote="edvancedengines"]With the best quality Ti-17 Professional Grade Retainrs the retainer OD is smaller than the spring OD. There is no reason for the retainer to be as large or larger than the spring.} Thanks Ed-I replaced my Manley Titanium retainers with a set of Xceldyne Titanium retainers that fit snug in the springs and are smaller then the spring OD,chambered the springs,clearanced the rockers to remove the rubbing marks and now the rockers have NO marks on them after several 1/4 mile passes.
