You are worrying too much about chrome rings. Cast Iron rings are OK but not as durable, However they do seat fast. Not sure if you can even get a decent moly ring in a 261 set. If you want moly, you may have to call the manufacture and see if they can make you up a set. I use chrome because I have them in my stash of parts. I waste nothing if I an help it. Chrome rings were sold for years and years. You will not have any trouble with them. Have the cylinders honed properly and break the motor in properly and you will get good service. I just took a 235 chevy I had in my 57 out. Built that particular motor in 85, used chrome rings, beat the daylights out of that motor, driving, cruising, racing. Never a moments problem,. Ran perfect when I took it out to replace it with the bigger motor.
