Gives you an idea of what a stock 4AGE head should look like...

And pretty much what a stock 7AFE would look like...

You said the block aready said 7AFE, so you know for sure which block you have, there should be a marking on the head stating 4AGE if it is the G head on it (F in Toyota is the Economy head and G is the performance head). If you can, maybe post a pic of your engine bay, should help us identify the head (since the 4AGE did come in many different variants, the head design could have varied a bit from the one I posted).

back AWAY from the drugs. i repeat. back AWAY from the drugs.

Judging by what you just showed me, I think it's just a stock F. now I think I should bash my friend in the head for saying it's a AGE. LOL! The one thing people always look at is the headers and they all say "oh you had this changed out? Nice." I seriously don't know if they know much about corolla's. Looks all burnt out too. I'll see if I can take a picture of it tomorrow first thing. Hope the quality comes out clear enough to see it. Don't mind the engine bay. It looks crappy as this car has been sitting around for almost a year and had nothing done to it.
