something got into the combustion chamber i think.. that's assuming u didn't mod anything to ur engine.. maybe someone do something.. like putting iron ball into the manifold ?

Naka aggressive cam ka ba sir undah? If oo, nung nagoverrev ka, tendency is valve float unles you are not using stiffer valve springs. Just a conclusion:

Nagoverrev ka, nag valve float, dahil nagvalve float, hindi lumalapat yung valve lip sa valve seat, inshort, tumukod yung partially opened valve sa compression stroke ng piston mo (TDC) causing the piston to hit the valve then nabali at yung putol na ulo ng valve ang nagcause ng pits sa piston crown mo.

Kaya sa mga gumagamit ng hi-lift na cams, make sure nasa preffered measurement ang valve clearance nyo ang use stiffer valve springs.
