if you pulled them off the rocker shaft ?, and slid them on the wrong shaft ?, then yes..its posb, you would have the top of the rocker off a tad, as well as the cam faces not riding on cam lobes on center, so yes, its posb !. just don't know how it would run though ?..or at all ?!..lol.Is that even possible without them being upside down. I vaguely remember thinking they only worked one way. I hope to have time to pull the rocker cover tonight.speaking of you tinkering with the rockers..i just gotta ask !..lol, any slight chance you put the rockers back in backwards ???..as in..intake on exhaust side, and exhaust on intake back on the shafts ??..lol.
