Set of Air Flow Research 215 cylinder heads with 2.100 intake and 1.650 exhaust valves. These heads were on our 2004 Popular Hot Rodding Magazine Engine Masters motor. Our 408 cubic inch small block chevy motor made 654 peak horsepower with these incredible heads on pump gas ! Countless hours of porting, flow bench testing and dyno work are in these heads. Heads have been disassembled, pressure tested, cleaned and bagged. Also included is a printed air flow analysis and printed dyno results. I was saving the heads for a special project. $2500
