Is that piston flat on the top?
@DieselTech that gasket looks like it was sealing all the way around to me, there is a little oil seepage from removal on one side. The up side has a good impression of the cylinder all the way around, shows good even torque. Half the time the gasket will be crushed on one side and not the other, the crushed side had the big kid on the production doing the torque on that side.
