If you look at the cylinder in the picture you can still see the cross hatch pattern from the original honing operation. There was no ridge at the tops of the cylinders either so am hoping the cylinders are useable as is. The engine is out of the car and on a test stand rather than an engine stand, completely disassembled but with the crank still in it. My intentions are to sell it once the problem is solved.

I would not really call that an acceptable cyl for new rings.Having said that it should be de glazed at the least.No mention if there is any taper?I also would use a flex hone for that operation as they are quick and easy compared to a 3 legged hone for de glazing.If you are close to a machine shop see if they will lend you one as the flex hone is probably around the 50.00 mark.Offer to give them some money and leave a deposit until you return.It also appears it was ridge reamed in a previous tear down.Your engine your rules.Just sayin.
