Cam lobes should NOT be centered in lifter bores, they need to be slightly offset in order to promote lifter rotation. That said there are two types of timing gear sets for FE, one with thrust button that runs via spring against timing cover & later type that utilise a thrust plate in similar fashion to small block fords. Make sureyou have the correct set for your application.
