4.6headers
Well a mixture of both. The 2009 2v is the exact same as the '04 - '08, which actually is the same as the '99 - '03 model 4.6. The 3v I would imagine they would bolt up to, but not sure, could be different head work to it, other than just the valve work. Also the under hood clearance may be tighter, as every new model is more and more cramped under the hood, so its mostly a guess.
