What would cause all 16 rocker nuts to come loose? One so bad it let the rocker jump off the valve. At first I thought it was just a bad nut on that one,, but they are all very loose. 16 bad nuts???

oh yeah, it's a 305 bored and stroked to 340 - I know, but I wasn't the one that did it.

Rocker nuts on a small block should be self locking type. You may have standard nuts and they will work loose. A set of new nuts would not be expensive. If there is enough stud above the nuts you could double nut them and lock them together. Are the nuts "rounded" at the bottom to match the rocker? If not do you have a rounded collar that matches the rocker? Take the time to give it a good look.

My bad. I thought this was a V8. The rockers on a 305 are shaft type just like the inline 6. I have had rocker shaft support nuts come loose and keep a valve from working. I would guess the nuts were not torqued properly to begin with. Try to get the correct torque settings and it should be fine. Gotta pay better attention, I gotta pay better attention....:0

Double check each pushrod, just to make sure they aren't bent. if the lock nuts were properly tightened when the last adjustment was done, they could easily work loose.
Good luck
Dave
