I read all the threads i could find about this, but none really answered my questions yet.. Which would honestly be cheaper? I have an 03 GT 5speed and would LOVE to have the 4v heads! I know the cams are gonna be one wallet killer but other than that what all is necessary? Intake, TB, headers... The only way i would do this swap is if i can find a set of used heads for $5-700 which i have seen recently when i was broke... I figured if i get them for 500 and can get them p&p for a good price along with a used intake and aftermarket TB and headers (which i was gonna do anyways) it would be a nice little boost in power and a very nice setup for the blower i am saving for down the road. The reason im going this route is, im trying to stay away from boost/350+rwhp until i can forge the internals, and i will be adding these part eventually anways.. Let me know what you guys think and any opinions/suggestions will be appreciated as always. Seems like this could be a lot cheaper than getting a whole used motor. My main question is, is it gonna be cheaper/more effective to get patriot 2v stage II heads p&p?? I have never seen a dyno from just a 4v swap so im in the dark here
