Here's my set up, PR3-3 Head, B20b lower, I snapped my timing belt and thought i lost my Valves, popped the head off yesterday and did I get lucky, No damage. I have scoring in the cylinder walls, and i can wiggle 2 pistons. Going to Replace the Rings and Hone the Cylinders, I need to Identify the pistons, because I don't believe they are stock, but I really just need to find out what Rings I need to buy...Noob here and Really need help! Here's the numbers on the Piston

6567M84
