Machine the head in two pieces. A top half and a lower half (not necessarily equal halves). The lower half mating to the block deck. Then you can machine the jackets to any shape you want. Also may make the ports a bit easier.
Getting the two pieces to seal might be a bit tricky, but the head bolts would clamp the two pieces together as well as clamping the head to the block.
Anyway it's one approach.
