tomustang said:FR500 or Cobra R heads
yeah that's why most of the people who run 5.4 heads have a custom intake fabbedhotmustang331 said:FR500 heads are just about as good as the 03-04 DOHCs...but they cost ALOT more. He can get the fr500 cams though.
Cobra R is a 5.4 style, and would need to rig a custom intake up to work. Something like a SERIOULSY worked 01 cobra intake. And besides that there were only something like 300 Cobra R Heads cast, you cant find them.
Ford GT heads are simular to the Cobra Rs, and again would need a custom intake. On top of that they cost $1221 EACH!!!! And from what I understand thats with no cams. So thats about $2500, then your going to need the $1000 cams, and the $1500-2000+ intake manifold, custom Kooks 1 3/4 LT headers (probably over $1000), and you will need a $300 TB, and some sort of a CAI.
Mach 1 heads would be a much better option as they flow 26X CFM stock and should make 300CFM ported. Cheap to buy on EBAY or something. Then you can buy the FR500 intake (2500 I think) or a stock 01 cobra...or one of the aftermarket ones available for about $1000....or teh shaker with a P&P mach 1 intake manifold. Plenty of options, and should go tegethor pretty easy .

Get P&Pd mach 1 heads
Custom cams
BB 302
FR500 inatke
tune
= usually around 450RWHP N/A vs a max of around 330RWHP for the 2V. Im going 4V when I rebuild.

If youre serious about making more power, i would advise to stop modding ur GT, and save up and buy a crate motor, and start dumping money into that. Then when you hit 100k on ur GT, drop in the crate
tomustang said:those 3V heads are expensive, you can only get them at the dealer or off a wrecked 06 explorer, 05-06 GT, or newer F series, then all the custom work to fit them wiringing etc...
4V heads are cheaper
