Wow so lots of different choices for the 4age head gaskets, with all the different 4age hybrids out there, I am really surprised there isn't more readily available information on this. I have seen 20v compared to the 16v but not the various 16v compared, does the 4agze have a specific gasket as well. What do the 7age hybrids use?Petros wrote: btw, all 16 valve heads may not do this, I think the early 4age have the same rear to front flow as well.
I always thought that tha a 7age would be a nice swap for the tercel same crank bolt pattern, better torque then the 4age, and a lower red line then the 20v.
