VALVE TOP CAP - SMALL SINGLE GROOVE

Standard top cap for small single groove collet type valves, AEA653 can be used as an alternative. Can be used for earlier 88G616 but it will sit about 20 thou higher in fitted spring height but fine for standards use. Both 2A11 and 88G549 seem to fit the original top caps and have been ftted on our recon std heads.
