what type of airfilter system do you have on the car?you may have sucked something small in and at that speed and rpm cause thats a clean looking chip..or could just be bad seating..i have extra valves if you need one to replace it.glad to see it does not fuck up the head tho i would just say bad valve at least it did not brake into the chamber

well at least you know if no pistons damage then it was not inturnal so it looks like you just had a bad valve do you have aftermarket springs? maybe its time to upgrade to Stainless Valves

yes I have aftermarket valvetrain, and that was a stainless steel valve. I filled up the night before and put a whole bottle of Prestone 0-60 Octane booster, would that have anything to do with that hole in the valve??
