Re: 4a head on 3a block wich head gasket?
Welcome to the list!
I would go with the 4a head gasket, everything else should align okay. I thought the aftermarket head gaskets were the same, but I never compared them. I suggest doing the mods and follow the procedure for my head gasket installation over in the repair guides section. Here: https://tercel4wd.com/forums/viewtopic.php?f=7&t=6059
How did you crack the head on your Toyota? I have really badly abused and overheated my 3a head a number of times, but I never cracked it. I did warp it badly, but it was still able to be resurfaced and the cam bore had to be redone to align it.

Re: 4a head on 3a block wich head gasket?
that's odd because according to this guy from the 4ac-powered forum, the 3a and 4a heads are the same except for the valve cover so the head gasket should be the same. check out his post.

if the part #s are different, they must be different though. pretty weird.
