Quality of AFR valve springs??

Are the valve springs (AFR part #8015) that came with my AFR165's (AFR part#1402) with the 8032 spring upgrade poor quality/junk/known to break/etc.? I had one break on me not long after I installed the heads (about 100 miles). I had taken it easy on the engine, not revving over 4000 ever (rev limiter) and when it broke, I was just cruising along, not beating it or anything.

Should I get better/different ones?

Thanks,
Rick

My valves were setup by AFR - they installed them and the springs. If you meant valvetrain (I assume), I think so. The tip of the rocker rides reasonably well on the valve (see pic). The rocker didn't come loose and was still over the valve. No signs of falling off the side.

FWIW - that pic in the previous post is not a pic of the valve/spring in question.
