07-08 Yamaha R1 Cylinder Head

07 Yamaha R1 Cylinder Head with cams, valves etc. Head was removed from engine when we purchased the bike so we have NOT seen it run. #1 piston had evidence of interference with exhaust valves. No imperfections were noted on the face of #1 exhaust valves. Valves were NOT removed for additional inspection. No issues were noted in a visual inspection of cam lobes, journals or valve faces. Sold for PARTS or REPAIR only because we have not verified it's running condition.
