Lash cap missing

I lost my lash cap on the exhaust valve while taking head apart, could I get a lash cap from auto zone or napa or somewhere? Do I even need it? Could I run the motor for a little bit before I get one thanks
If this is a honda/clone or predator engine and it is on the exhaust really kinda need it to keep the retainer locked on. JMO
No not with split keepers but with stock retainers...but I still do run lash caps on my split keepers on both valves.
