Thats the cast at the bottom of my head. I cant find the webpage that had the directions on how to identify it, but can anyone tell me what gen my head is?

 

-Brian

the box around it means it's a generation III i believe.

THats what i Had thought, but didnt know for sure.

 

Good news is there appears to be no damge to the head.

No cracks between the valves?

generation 1 turbo head - plain "EA82" on the bottom

generation 2 turbo head - "EA82" with a line under it

generation 3 turbo head - "EA82" with a box around it

 

Hopefully this will help in future referance for people since you already know the answer

The same applies to nonturbo heads too doesn't it? My 88 XT nonturbo has the line under EA82.

There doesnt appear to be any cracks:

Wiping the dust off this thread cuz I don't wanna make a new one. Aside from the identification markings, what is actually the real differences between the phases, the casting process and/or head design?

The exhaust ports have a bit more metal in them as the most common issue is the coolant jacket to crack into the exhaust port.
