Let's hope it doesn't have a bent valve.  I built one of my 22re's and  when I went to fire it up, the #4 exhaust valve bent.  I think it was something stuck in the valve guide from the machining process.  Then after I pulled the head, cleaned up the valve guide and replaced the valve, it didn't want to start.  Then I realized that the crank needs to be set at 5 degrees before you line the distributor rotor up to the #1 wire.
