We need a pic of the FRONT of the cam, directly looking at each gear.

S13 cams (240/248) are ORANGE on the exhaust, and GREEN on the intake...as you know. S14 is opposite.

...

Now, how do you know which is which?

The dowel pin.

The intake cam has the dowel lined up with the number 1 cam lobe.

...i.e. if you lay the cam down with the #1 lobe facing directly UP (12 o'clock), the dowel pin will be in the 12 o'clock position as well.

So...if you have an intake cam with a green stripe...you have S13 cams.

Easy stuff.
