Vortec heads are complete with valves, springs, rocker studs and push rod guides. Heads have 30 hrs run time and are machined by Pace Chev. to accept a .0550 lift. Will sacrifice for 300.00. These heads produce very good torque and h.p. on SBC. With these heads and a moderate Comp Cam, my 18 ran a solid 70+ mph gps. Reason for selling: building a 383.
