Engine casting numbers

[JTTOKA]

I searched and didn't find anything that told me, where to find the engine casting numbers
Or for that matter head casting numbers.

Im hoping to I can figure out which engine is in my car. The car isn't a toyota but I'm pretty sure it's a toyota 2-tc or a 3-tc.

Any help with this would be greatly appreciated.
And I have no problem searching again, if needed.
Thank you
