Are the vortec heads that came on trucks the same as gm sells. Is there any better numbers to look for?

if you buy new castings, the only difference is the 906 castings are BARE, and the 062 castings are complete. If you run them don't forget to machine the guides if your gonna run regular z-28 springs. Stock vortecs don't come with a dampner and they will mess a motor up without the porper machine work for z-28 spring.
