Mysterious problem

Hey fellas,
Ok I just got finished installing a set of Comp cams pro magnum roller rockers on my 85' 318. Its was an easy process but when I was finished and went to fire the car back up its only running on 4 cylinders 1,2,5,8 aren't firing off. They are getting spark, I can put a plug on those leads and it sparking. I never even pulled a spark plug wire. I have triple checked the timing and firing order and still no luck. I also rechecked the valve lash completely 3 times.(thinking that maybe they where adjusted to tight and not allowing the valves to close)
I havent had any troubles with this engine ever. It was completely rebuilt about 4k ago. It ran perfect right before changing the rockers but now its a no go. Any help would be great.
