Hello, Is there already a thread that has detailed head specifications? If so please point me that direction if now can someone please help me out? I have a 96 4.6 mustang GT motor and I am going to do 2 different things, the first is rebuild the stock heads (I believe they are 2v) so i would like specs on those heads, and the other I am going to get a set of 03/04 cobra heads either for this motor or another i will be building in the future so i would like specs on those heads also but mainly the stock heads. Any help would be appreciated.

Don't waste your money on 96-98 Non PI heads. The 99-04 GT heads aka PI (power improved) flow much better and bolted onto a stock 96-98 GT motor bump the compression up too. Makes for big gains on that motor. Find a pair of used PI heads or even summit racing and jegs sell them new.
