Case 580c rebuilt with clevite

Well all, got the head back and installed everything today. This is what she sounds like, no smoke from the stack, smoke from the crank breather. Let me know what you all think; I heard a chatter, sounds like the valve train? I found some 207 videos on youtube and it sounds the same. I have this for break in, ten minutes no load 1000rpm, another 10 minutes at 1800rpm, no load, 2/3 throttle some load at 30 minutes, on
