Forgot to mention that more manufacturers are making more of an effort to
provide a wider selection of injector spray types, geared towards 4V heads.
Dual cone injectors give better valve targeting. There is a reason that
Siemens, Delphi, MM, and others are selling a lot of bent dual cone
injectors. The reason is the manufacturers want to acheive better
targeting.
