Cast or aluminum intake?

Ok I know nothing about strokers;
but IMO,
With that small cam, aluminum heads and 9.9 will probably let you run on 87E10, which can be had anywhere. I had a 367 like that, with a tad more C/R. It was DYnomite. I cannot imagine stroker-torque. But I'd sure like to take one for a spin someday.
