So why do my valve springs look like Christmas in July?

Started the teardown process this past weekend and noticed the valve springs are different colors. Some are red and some green, six red and six green. The engine was from a donor bronco, supposedly a 1974. I know my 72' 200 has all red springs, just curious if anybody knows why there are half and half on the newer engine? I'm guessing either somebody rebuild the head already and went with stronger springs on the intakes (or exhausts) valves for some reason. Thanks!
 
NOt sure why it was done... but it's like a Christmas present every time you open your valve cover. Who wouldn't want that?
 
If your exhaust valves have rotators then the springs are shorter then the intakes they use different colors so they can ID them during assembly. :nod:
 
Reds are exhaust and greens are intake, I didn't see any valve rotators. I'll pull everything apart and report back.
