after pulling my valve covers and snapping some pix i noticed that they're painted in sections, red and white.  if they're facing different directions does that mean im getting float and the springs are turning?  or is this normal?  i dont have any noises and it runs great.  just curious if its something i should look into.

is it worthwhile to upgrade the rockers or anything valvetrain wise?  its just a basic 454 setup right now...  ive always done my mustangs with alum heads and 1.6 rockers... im guessing run of the mill bbc's are 1.7's?
