started to open up the 455. Turkey tray and lifter valley were not very coked up but the intake manifold had been removed sometime earlier and cleaned up. The turkey tray had been cleaned up (wire brush marks) and reinstalled.

However this was a "bit" of a surprise:

Bent pushrod on the #1 cylinder. This is the cylinder that only has 25# of compression and the one that leaks air into the crankcase when air tested. No leaks noticed on the intake or exhaust.

Any ideas what I'm gonna find when I pull the head tomorrow?
