I have a Gen 3 and am looking at adding some power. I have a guy local to me that is willing to sell me some Gen 3 heads that he says have been ported and have aftermarket springs and valves in them. He is willing to sell them to me for $2500 as he has had them laying around his speed shop for awhile now.

My questions are can anyone tell from the pictures if work has been done to them? I am pretty much an amateur when it comes to cylinder heads and cam shaft specs etc. Seems like a decent price, but if they are just stock Gen 3 heads then I would not want them. Says he also has a matching cam and I would see about an additional 80hp at the wheels.
