Trying to figure out exactly what kind of heads are on my friends car. I know they are AFR heads but i want to know what volum and everything else. Its a 383 lt1 and the head on the driver side has front stamping which read "H24077-10" and then over to the side which i needed a mirror to get to its got a couple other numbers that are stamped much smaller>>> "A041". Can somone help me out with these. My friend bought the car built, i dont know why. Im trying to figure out the cam specs but thats nearly impossible without a cam card.

thank for your help in advanced. i cant drink for ****
