just rebuilt the motor, wisco/piston, hotcam2, ran great for a bout 4 hours then seized, what happened was the cam sprocket bolts came loose and fell into the crank, i was able to get the bolt out. my question is how do i keep the bolts tight,(had red locktite on them and one still cam out)

 

That's all we do , clean the threads with contact cleaner and use red (high strength) locktite ..

 

I think you did what 99% of us would do. I would think the red Loctite would hold it.
