Used Big Block Aluminum cylinder heads for sale. 440 Source heads. Upgraded double valve springs, otherwise the heads are untouched, never milled, or ported. Bought bigger heads so these need to find a new home. Heads are still on the motor currently. These sell new for $1000. My springs are for a higher lift came so these already have the upgraded spring. I have these on a 500 cubic inch motor that dynoed at 600 lbs of torque and 580 horsepower so they flow really well. With upgraded springs I am asking $900.
