Used for about 6000miles. Have larger valves, port, bowl and chamber work. 59cc chambers. They are ready to bolt on with CC 987 springs, stock locks and retainers. Purchased from a friend for my blower project, decided to sell the car, so I am looking to get what I paid for them $950.

Flow sheet can be seen here:

Heads were re-worked a bit after this flow sheet was done and flow approx 3 cfm better across the board.
