I found a set of low mileage used patriot performance stage 2 heads for $700. First off does this seem like a good price? Second off I only have basic bolt on's bbk pullies, off road x-pipe, catback, cold air intake, 4.10's, king cobra clutch, triax short shifter. Ive been trying to sell my car to upgrade to a mach 1 or cobra but have had no luck. My question is if I bought these heads, a decent cam, Pi intake or bullit intake, plus all the misc. parts gaskets and such needed to do the swap what kind of price am I looking at? Less than $2000 in parts? Also how much would be a fair price to get these parts installed at a shop? Would I be near or at 300rwhp? If I decide to do this I would be piecing it together over the course of the next year and hopefully installed next summer. My car has a 125k miles on it but still runs strong. My other option is sell my car for what seems like nothing $4500-$5000 if im lucky and save for a 4valve cobra or mach 1. What would you guys/gals do? Please respond quick so I can make a move on these heads if need be.
