These are not interchangable. The ABA, i believe, uses a US specific head, with a similar bottom end as the AGG motor. The early ABAs apparently came with squirters for pistons and the late model ones didn't. There are different schools of thought on their necessity but many are adament that they're really quite useful.
A common conversion in the states is the ABA 16v motor. They never got the 2.0 16v ABF motor domestically, and there are probably millions of 2.0 8v engines that can be had for pennies. The block heights (aussie 2.0 8v and ABA) are the same, which are different to pretty much every other 8v, as is rod length. The change the pistons and use any 16v head (PL heads are common as **** in the states) = effectively 2.0 16v ABF. It's a lot cheaper to send pistons from europe than it is short motors.
Basically, they make 16v motors with their block and older CIS heads. You could do this just as easily, but it's not nearly as cost effective because 16v motors/heads here, are sufficiently rare too.
oh how i wish i spent money on a cross flow... so much more space!!
