Question with 6 bolt swap

[combatmedic]

So my 1g head is scrapped so I am going to buy a 2g head to do my 6 bolt swap. I know I have to drill out the holes but I am confused about the CAS. Do I have to use the one from the 6 bolt head or can I use the 2g one that sits under the cam gear. Also what about the crank sensor can I take the one from a 7 bolt block and put it onto the 6 bolt block??
