Help! Small block 360 has a knocking sound

This is what rodknock sounds like
(It flutters after you let off, yours doesnt do that, so time to pull your valve covers)

ok, what do you suggest I look for? I have pulled the valve covers and watched it run, and everything is oiled and working just fine. No bent push rods, nothing was loose, all valves are opening and closing just fine.
