These heads were ported and polished by Maurice Petty and Associates in Level Cross, NC. They have new correct valve springs and new exhaust valves. They also come with scorpion roller rockers and pushrods for a stock block. Anyone with any questions send an email to sydwyndr@triad.rr.com for further information. These are not my heads I am posting for someone else.
