b18c1 uses a p72(?) head, which uses a slightly different intake manifold bolt pattern.

Depends on how many lbs of boost you plan to run. If youre gonna keep it below 10, just go with the b16a, but if youre planning on taking it up to 11, 12, 13 psi on a stock block, def go LS. Although you will see higher hp numbers at the same boost level on a b16, the torque will still be down there. The awesome thing about LS motors is how the torque and hp numbers are close to each other.

I was planning on going that route in the future, b16 head.
Instead I am thinking of buying another B18 block and sending it to AEBS or that place in hawaii for the full work around./

I voted B18B. More displacement = more betterness. Less rotational mass in the valvetrain, too, if you happen to be anal about that kind of stuff.
Use of a B18C bottom end with your current head would be nice though, since you could reassemble it with head studs, a good head gasket and little stuff like that.
