Ok well i found out the problem.....
You guys are going to mash on me so hard but after I did the second head gasket job I didnt fill it back up with oil I was to excited. I didn't think about the oil that had got lost from the head.... Anyway I put a bottle of STP oil treatment in it and another quart of oil and let it run for about 10 minutes. The knock is still there but I am pretty sure its in the valvetrain somewhere....
