That crack is made that way, can see it in pic below, upper manifold.
Also, If I remember correctly, the oil dipstick has to come out to get the passenger side manifold off
. One bolt holds the dipstick bracket to the engine block and it the goes into the engine block with a o-ring for sealing. The manifold won't go over the bracket that I could find, like I said earlier, just a bunch of grin and bare it moments to get the manifolds off. (May be because of the heat shield, I do not remember, been a while since I did the work
)
Here is a link to my HUMMER page at Photobucket so you can see some of the "parts" and what I removed to get the manifolds out.

HMH2SUT, You are welcome on the part numbers
Good luck, Ed
