on bb fe/385 fords i would stick with the steel/iron, best practical all around. on our bb racer, the aluminum works fine, but doesn't seem like a lot o difference, just changes up your driving style into and out of apex. personally i think it works the brakes more, might be just me shakin the old 60's/70's feel of flywheel doom with the alum. had one explode dragracing in the 60's w/o a scattersheild, that you don't forget.
