Set of aluminum heads 1.94/1.50 valves, New valve seats and bowl blend by Batten performace, 7/16 Screw in studs w/guide plates. I was told the chambers are 58cc .I don't know much about the heads except that they came off the Quaker State Dirt track Sprint car. They are for center bolt valve covers, but I also aluminum plates to convert them to perimeter. They DO NOT have valves. Email if interested.
