the difference will be the bluetop to redtop big port.
4agzes have the same head as n/a

ie ae82 early aw11 to ae92 late aw11

I haven't seen any 4age with the mounts in the head, They might exist but i haven't seen any.

Thats not a engine mount, its used to support the metal radiator hose splitter, all 4age FWD have the mounting holes coming from behind the timing cover, the reason other 4age's might not have that little mount is because they have a one peice hose from radiator to waterpump.

You must spread some Reputation around before giving it to Poggy again.

Poggy is right again.

can someone else shed some insight into this ?

thaty might be a nice way of identifying your pistons... although that one is looking a little out of round ahahha

dead right, if i could find my acl parts disc i could give you the exact part numbers for both (damn my lappy crashing and losing the program).
as for the ring gap, all the bigport 9.4:1 pistons have the same ring gaps. they only went smaller on the top ring in the later smallport 4age piston.

all aussie aw11's had 7 big blocks.

yup, and never ever came with oil squirters.

did they have the provision to fit them?

If by "provision" you mean drilling and tapping out the pressurised oil gallery internally in the block, then yes. But for all practical purposes, no.
