hey buddies, I have a question for you guys.. how can you tell if a 6.0L engine is a Lq4 or Lq9 by just looking at them from the outside? the casting on the Lq4's heads are 317's right? might be wrong.. that's why I'm asking.. in case I'm right, what does the Lq9's heads say? or is the another way to tell??
thanks!
