i just bought a ported/polished head for my d16, and the seller said it had crower valve springs and retainers on it. im pretty sure the crower retainers have the stamps on them, but these dont. also, is there any was i can tell if the springs are crower?

here are some pics.




Sorry about the size...

i took one of the retainers anb valve springs off, and the springs have green and red markings on them. do the stock ones have this? the retainers weigh about 5.6 grams, and crower says they should weigh about 5.5, so its close, but what do the stock ones weight?
