This is a set of New, still the box Champion iron CNC cylinder heads. These heads have never been installed on an engine. The heads have 46 cc chambers, 1.77/1.55 one piece stainless valves with new springs, retainers and locks that will handle up to .500 lift. $1095 shipped.
The heads are set up for a flat tappet cam, change the springs and check the retainer to guide clearance and they will be good to go for a roller set up.
