Some day when you don't have a headache but really want one just go here,
Welcome to the California Air Resources Board
I think there are advantages to the MPI over Howel but your call if justified by the cost or make sence for your needs/wants.
It is a more precise fuel delivery having an injector spray directly into the intake port at each cylinder as opposed to having air/fuel mixture travel the unequal lengths of the intake manifold. You also get to lose the cast iron intake manifold whitch in my case had to be replaced either way due to having the carter YF 1 barrel.
