I hate to say this since Snow800 has made a great effort at getting you the stuff you need. However, I don't know if his info posted as he intended.
Typically, in a multi-fastener job like the case halves, one would start in the center and work out using a diagonal, criss-cross pattern as much as possible to keep the pressures as even as possible. (Of course, you also do the tightening in two or three steps to further help minimize stress or pressure in any place.)
Round head patterns involve diagonal sequences.
Most fasteners on the engine torque at 18-24 ft/lbs depending on their diameter. 38 ft/lbs seems high to me. It could be correct but I'd check that to make sure since too much torque is not going to be a good thing.
