Need help..

I have 2L Zetec engine in very good condition, crankshaft bearings are STD, but he give me a pistons separately and I dont know are they from that engine..

I have big-end bearing shells from that pistons ( con rods ).. And they have part number 928M6211A2F and - Fm 4 19 1 ... Are this bearing standard?


And second question is how much do you put, have piston ring gap..? When you build ZVH...

Thank you,
