Jacques, You can used the 3.0 Heads. If it's a 2001 block you need to make an adapter plate to fit the Lower Intake Manifold. Jiako had to do this on his engine. If you uses an older block 98-2000 you need to either use the 2.5 heads or get an electric waterpump. On the older block the Lower Intake Mainfold should bolt right up. Bnoon has an older block with the 2.5 heads and can tell you about it.
About your modified intake, If you get some pics on the computer email them to me at lee@coxfinancial.com and I will host them for you so you don't have to worry with it. I'm sure we are all very curious about your setup. I'd like some full mechanical pictures to try an modified design with. I have a few intakes sitting around for that. Regards, Lee
