Engine bracket question

So I think I have my bracket issue figured out...the passenger side bracket biscuit holes needs to be redrilled so the biscuit bolt moves fowards. I know the bracket is on wrong but with it being like it is the engine is centered and not offset in the car. * first pic

Secondly I’m fighting the k frame/ biscuits so that they sit flush on each other. I have a gap on either side with the engine lifted and if I let the engine down, only one side will sit almost flush. My question is, do I need the thicker mounts now to fill the gap or do I lengthen the k frame slot a little bit so the biscuits can sit down further? What cars needed a thicker biscuit? I’m afraid tho if they sit down too far the oil filter will hit the torsion bar as well.
