ARY and APY are the head the same?

Yep, the casting is the same.

There are 2 actual castings large port and small port. The VVT and the breathers and stuff are all added by the componant parts that complete the head
 
Good as my APY one i ported i found some cracks and it needed new guides fitting and seats cutting and tappet bore worn due to the oil pump going so to restart with a better head would save some cash
