There are baffles in the valve covers for the PCV connections.
I need to check back on what rings I used, I don't recall them being chrome but my memory is not the best on the details.
I am pretty sure the valve guides are not sloppy loose but again it has been a while since it was put together.
I'm not anxious to pull the engine and tear it down but if I need to do that it will be a winter project.
