We ended up using our Performance Tools cylinder hone from Summit to knock the ridge down and hone the cylinder, but in the end it didn’t matter. We still ended up with a compression ring coming out in two pieces for cylinder number three and a crack at the wrist pin for cylinder five. Normally taking the ridge down will avoid these problems, so we suspect these issues were there before we took the pistons out. Interestingly, cylinder five also had a concave lifter lobe and a partially rounded-off cam lobe. We aren’t sure if that had anything to do with the crack, but there it is.
