I have a 04 awd 3.5L pacifica. And the timing belt went, and took out all my exhaust valves. After completely disassembling the heads, I noticed all the springs are different heights.. so, I want to replace all the valve springs, intake and exhaust. sounds so simple right?. I cannot find any springs for my specific vehicle and year.. I tried calling Summit and Jegs.. they were no help. I even messaged mallory... they said they can't help. There is only one Mopar spring, it's 20 bucks a piece... was Hoping for something a little stiffer than stock if possible. But anything will work
