Bought a Van......

Ok, as good as this runs, I discovered something. I tuned my ear, even drove it with the dog house off, I hear at the top of the valve covers something that just didn't seem normal. The guy I bought it from gave me new Comp Cam push rod guides with it and said on his trip to Florida, one cracked. So, I pull the drivers valve cover and it has Comp Cam roller rockers, mounted on adapting stud mounts to 3/8. Some of the rollers were half off the valves. I rotated the engine till valves were shut and some of the rockers were so lose I could almost pull the roller off the valves. No adjuster at the push rod, but I could tighten the nut that holds the rocker and take the slack out, but not before it was solid on the push rod and valve. I'm pulling them off and putting original magnum rockers and plates on. Got 3 cylinders done before the "Eve events started", and the factory magnum rockers are fitting as I would expect. Any ideas what may have went wrong with the comp cam roller set up????
