Spoon stroker kit

This spoon stroker kit says its only for a b16b but why wouldn't work with my b16a. It comes with crank, rods, pistons, rings and a new head gasket. Other than having the head resurfaced what other parts\Expenses would be required or needed?

I would also like to know the answer to this. I tried searching a few days ago and couldn't find a dammmmn thing about it.
