You can bolt 4V heads onto any GT block, it has been done many times in the past.

There is a difference between the 99/00 and 01 & up block.

The 99/00 were Windsor block, whereas the 01 & up were being made back in the Romeo plant. The reason the 99/00 were made in the Windsor plant was because of a fire in the Romeo plant. The block are slightly different.

the bolt patterns are the same for the heads but they are a 4 bolt main. that is the difference. the base of the 4v and 2v heads are the same, but the top of the 2v heads are slimmer that's why they look so different.

and if you think the 99-04 are 5.0 you really need to find another car forum.

The conversion to the cast iron block to handle the heat/stress of the 03 - 04 Cobra powerplant, along with its accompanying added weight for the Terminators over their aluminum blocked 96 - 99/01 counterparts, is analogous to knowing your ABC's. Almost something you have to know...

Wait a minute....... now, I KNOW Michael Jackson sang that song! So this whole 302/4.6 thing is just a ploy to distract us from the real truth.
