Made it 95 miles since I started the motor. The only thing "new" on the motor are the gaskets and the heads. Today it was running fine, then suddenly as I turned a corner into a parking lot, the entire sound of the motor changed. I got it home and found two broken valve springs on the drivers side, #1 and #3 exhaust.

I'm due to be back in Ione, 85 miles away tonight after work, and tomorrow be another 100 mile drive away in Moyie Springs, Idaho in this truck. I have a feeling this will be a long night.
 
Ouch! Are you sure you're using the correct springs for the cam that is in the engine? :confused:

Big cam, stock springs. :crazy: :shame:
 
Nope. Checked the valve springs before I put the heads on and they checked out OK to run with this cam which is only .516 lift.

Got the springs replaced a bit ago. Re-adjusted all the valves and now theres still a ticking noise coming from the pass side bank that just wont go away. Springs are all ok still... and it runs like it should again. Just still has a darn ticking like a collapsed lifter.
 
Much better picture:

Lots of pitting on the surface of the springs. I think when he rebuilt the heads, they just slapped some used valve springs back on it. They aren't stock valve springs cause the good ones check out as being able to handle the cam, but they definitely aren't new either.
