Nicely ported aluminum pushrod heads, have stock valves, coated stock springs, stock retainers, fresh valve job.
These heads didnt sacrifice any flow down low just for big high lift numbers, they will really wake up any motor, even one with a stock cam.
flow numbers before and after portwork as follows:
pictures of heads can be seen here: http://images.couldbeworse.org/v6heads/
asking 500$ for them shipped to anywhere in the lower 48. There is much more in these heads than that and they have never been bolted on since all the work was done so they are good to go right away.
