take a look at sites other than MMR.

do a search for 2004 mustang engine then go to s/c DOHC cobra when it asks you to pick a trim.
$6,000 for the engine.
thats far cheaper than buying MMR 4500.00 heads and having to replace the bottom end..... . .. . .
(not saying you should do this, just saying its an option other than MMR)
