Rail Rockers on 289 Small Block Heads

[sleeperstang]

Right now the valve is stuck in the engine about a 1/4 of the way in and it doesn't come back out, so I believe it is bent.

All the other rockers looked like they were operating ok when I had removed the valve cover and cranked the engine, and this was after the engine had been running for about 20 minutes at high idle.

I was only trying to let it break-in when all of a sudden the engine stops after hearing some metal pinging, like something had collided. That's when I took off the valve covers and had my brother crank the engine, only the #5 valve was stuck and it was tapped a few more times apparently by the piston.

So far that is all I know about what happened with the engine. If you have an idea of what happened, I'd really appreciate it.

The situation is that the engine is under warranty (it was only the second time I had turned it on) and I wanted to make sure that I hadn't done anything wrong when attaching all parts to the long block. The machine shop took care of the long block build up including torquing the heads on and checking spring height.

I just want to get as much info so that this guy doesn't try to dip me by doing some Mickey Mouse job on the engine when I take it to him on Saturday. I really appreciate all your replies.

Keep in mind this is the first engine of ever bought or built up, but I did read tons before doing any of the build up myself and made sure I torqued everything to specs as well as used the best seals and gaskets possible.

Thanks again for your help!
