honestly this first video, might have been made about almost any engine,
and most parts, and no brand of parts is flawless,
as all parts given enough stress, and time , will eventually fail or wear out!
that this happened is not surprising as it might happen in any engine, but it's a valuable learning experience,
and might help you justify spending a bit more on higher quality parts and doing research before buying parts.
mis- matching components, excessive valve spring load rates
,lack of adequate oil flow rates, high oil temps, low oil pressure,
less than the correct clearances, incorrect valve train geometry,
all , of those factors and several others, can and will result in much more rapid valve train wear issues
shrapnel screens, magnets, frequent oil and filter changes,
and constantly inspecting the valve train helps limit or prevent extensive and costly damage

valve train shrapnel screens
its fairly common practice for race engines to install a course mesh screen over the oil return holes in the block to limit the travel of fragmented valve train components, should something rather nasty occur and bits and pieces of fragmented valve train find their way into the lifter gallery...

cast roller cams and high spring pressures don't generally work well
running a cast core roller cam on the street with significantly more than MINIMAL spring pressures for the intended application, IS JUST asking for valve train problems, but a balance must be maintained, if the valve spring is too weak and allows the cam lobe to throw or loft the lifter at...
