What Is To Ring A Cylinder Head???

Did you just hear them wrong and hear ring when you should have heard ream?? Reaming the cylinders means that the cylinders don't neccessarily need to be bored, so what they will do is use a ridge reamer to remove the overlapping cylinder wall from where the piston reaches it peak to the top of the cylinder. Then they will most likely just hone the cylinders unless you want boring done.
