84 4kq injectors

[RICHARD KROL]

How important is the cone spray pattern on fuel injectors?  I set my injectors up in a home made rack the other night and did a flow test.  The flow rate seems to be nice and even but the pattern was bad.  Some would spray a partial cone and one was spraying a split cone.  They didn't look nice and even.

My injectors are the early style p/n 0-437-502-023 with the single O ring.  Would cleaning them help or should I buy new ones?
