Does not tell me what rings I need. I wouldnt have posted them if they had not been for a 318. Like you stated, I dont know what rods they're meant for, or what rings they need.
The compression height tells you they are for stock 318 rods. You should know that if you are looking at pistons. If you don't then you need to call somewhere like Summit and talk to a tech guy and they can fill you in.
