I saw an a12 head at a mates work place. It had intake ports shaped like this "0" not "o", i.e. oval and the same vertical orientation as the the zero. I couldnt find any numbers on the damn thing that resembled the format of numbers given a few posts ago regarding GX heads. Just wondering as he'll prolly throw the head away or something, would seem like a crime if it is really a GX.

thats a GX head alright, i just went out and looked at mine to make 100% sure, if the rocket covers not on look at the valve springs and see if they are double (one inside other) as this is a sure sign its GX too.
i know a good home for it if it needs one!

Found one thread on this with good info.

Here.
