Comp valve keepers- Is this an issue??

My dad and I are putting together a low buck 360LA for his D100. When he went to check the Comp retainers and locks I picked up for his new valve springs, he noticed the new locks are much shorter and don't go around the valve stems as far as the stockers did. Why is this and will it cause an issue?? Should I send them back? The only reason I got him new locks was that he needed 8 new ones for his new exhaust valves anyway (different groove count than the old ones), so I got him the 606-16 Comp kit that comes with all 16 pairs.
