puzzled on weird engine noise.
Have a 06 seuc 103 cvo. Was having some valve train noise lately and had a wild hair and ended up redoing the whole motor. Now for some reason the noise is louder, and doesn't sound healthy at all. Was just a faint normal noise before. Sounds kinda like metal to metal of some sort. I even took a scope camera and went in the cylinders to see if i could find anything but couldn't see any scratches or marks anywhere. If i listen to the motor running its mostly coming from the front exhaust valve, and a little from the rear exhaust. Can't really tell any noise from the cylinders or anywhere else. I put in new pistons, lapped the valves and put new seals on them and nothing looked wrong. I have a set of woods tw5-6 cams and woods lifters also. I have tried messing with the pushrod adjustment but doesn't matter which way i go with them it doesn't change the sound any. I am kinda stumped here. Not sure what else i can look for other than just tearing down the motor again. I even clearanced out the rocker boxes so the springs weren't touching anywhere in there. Any one have any other ideas what else to check?

I'd still look there first.
