With out removing can you test injectors?

Sorry if a silly question

There are plenty of other items that also need to be replaced that are not included like flywheel, clutch, flywheel bolts that isn't traditionally part of a longblock. The reason why the AOS was eventually added to what was included was because shops were using non-genuine ones that were failiing; same with the oil filler tube and even the oil cooler itself after SSF had shops again reuse these items and cause damage to the rebuilt engine.

However, injectors have always been recommended as part of the RND installation directive but the reason we don't include them is that shops want to source them and sell them to the customer directly, so we let shops handle purchasing these parts and other components required for installation.

Since all RND Engines come standard with an IMS Solution, they would have the spin on oil filter adapter and spin on filter.

Who do you know if you have leaky injectors?

Per Pelican Parts they are either $33.75/injector for Bosh OEM or $306.37/injector for Porsche ones. Not sure what's the deal there price wise as Bosh is the OEM supplier and the part numbers seem to be exactly the same between the two.

There are more knockoff garbage ones than good ones and it is very difficult to tell the difference, boxes are the same and markings are almost exact. $33 sounds about right, and $300 is thievery. Definitely buy from a reputable dealer for the best luck.
