Only the junkyard vortecs are likely cracked.
The trucks these came on had a intake gasket cooling
problem that caused the engine to loose coolant and overheat.
That what makes any head crack.
if you go for vortecs buy new castings.
The only vortecs in the junk yard or on evil bay are cracked ones.
The good ones get rebuilt and reused
Buy new and you won't get stung.
The GM bowtie vortecs rock.
The engine quest EQ lightning vortecs are very good too.
