I might be going another route, instead of my stock heads with port work I think In going to go the aluminum route. I know Trick Flow heads are killer, but they're also very pricey. Anyone ever run the Patriot heads? Ive heard on these that the springs supplied with them dont have enough pressure and need to be upgraded is this true? Also what about Pro Comp heads? I know the Pro Comp rockers are dog **** and assume the heads are also. My motor has an F303 cam with stock bottom end and windage tray. Also going to be running a Edelbrock Victor Jr with this setup will I have any problem with fitment on any of these heads? Thx Chris
