What sort of questions do I need to ask the machine shop before deciding what sort of rings?
More than likely I will be going .030 oversize, won't know until I get my hands on the block from the marine engineer who is removing it (one cylinder was very low on compression, so need to see if it's a valve problem or damage in the cylinder)
