Pistons dont fit in block.

Hello i decided to re ring my chevy 350. I honed the cylinders with 400grit stones and bought new sealed power moly rings ze251k, now i tried to install the pistons in the block but couldnt. i bought the piston ring compressor and applied light oil to both the piston skirts and cylinders.

I noticed that piston stopped at the second compression ring. I hit it alittle hard and forced all the piston in but stopped, i didnt want to break anything. I then decided to pull the piston out. now there is a grey mark on the cylinder wall were the piston rings were.

I made sure i had boots on the bolts and not hitting the crankshaft. Also i made sure the rod wasnt hitting anywhere. And there was plenty of oil on these parts.

Help is really appreciated.
