Do these 3b injectors look right? (1 Viewer)

Hi its my first time taking my 3b injectors out and i noticed all 4 have a little creator type divet around the pintle each one slightly different size from one another. The divet area inst concentric to the pintle either

Is this supposed to be there or is it wear marks?

Do i need all new injectors?

Wear is not discernible by eye. The non concentric circles are probably from the swirl pattern in the combustion chamber. You need to get them bench tested. If they are not up to spec, the injector springs and nozzles are replaced and calibrated.
When/if you get them rebuilt, do not touch the tips.

I just had my injectors on my B rebuilt. Originally brought them in for just cleaning but they were all bad. Cost me about $265 I think.
