Yes it takes the oil right from the oil galley, not the cam like the older stock and Mega blocks did.

As for restricting the oil IIRC my Mega had an .040" restriction. Obviously is you choose to leave the one that comes in the block the only way to increase or decrease the orifice size is to remove the heads. So IF you want flexibility to change it then you would need to do so at the heads.
