Hey all - Started head gasket job this weekend. Pulled my head off and noticed that the are different carbon markings on each piston. Does this indicate anything i need to be concerned about?

Thanks - Scott

What kind of pulse width and timing are you running on your tuning?

You wouldnt. I assumed you were using EFILive.

Pattern depends on condition of injector nozzles, height of piston out of bore at TDC, temperature, etc....

You're fine.
