I'm looking into putting in a set of cams this week because I have my heads off to change a set of head gaskets. I'm looking at the trick flow stage 2's and was wondering how they were. I know i have to change the cam gears and springs and retainers and I got a way better deal on the trick flows compare to the comps. Let me know what you guys know about the trick flows. I was also wanting to know what a shop charges for a tune.
