did i rev my engine to much ??

todayi was leaving school started the car and reved it up alot and constantly whomped on it i know this is bad but wat could it do to my engine. i think i might have over injected the engine i think i was leaking gas not sure no lights came on and all the gages were fine should i be worried ???

 

I try not to red line it to be safe, but you will damage your lifters at around 6200 rpm.
