Looks like the HX manifolds are starting to become a problem. I think cracking manifolds are fairly typical of cast iron manifolds and aluminum heads, due to different expansion characteristics. Lots of newer models have gone to tubing instead of castings. Ford started doing that about 20 years ago.
