spiders on tops of pistons **pics added**
Tore down a low mileage motor pulled e7's off and cleaning light surface rust with motor sideways for debri to run out and cleaned everything spotless.
But what I noticed is small little spiders on the tops of all the pistons like spider cracking of some sort or maybe from detonation IDK. Its so minute you cant feel em, only see em. Are these hypercruectic pistons? should I be worried?

If they are all that way I'd say it was because of too lean a burn. Looks like "spalling" to me. Do the splark plugs by chance have little spots of melted aluminum on them? If so that's what it was.
IMO.. they will be fine. Even if you were to boost the engine with a power adder. Don't just run it w/o looking into the A/F. make sure its getting enough fuel or else it might become a long term problem.
