What PRO action cast heads would work better for me, the 220 cc or 200 cc heads?? Dirt track stock car, 2900 pounds, solid cam, 383/406 motor 12:1 comp., modified holley 4412, flows 650 CFM or so, cast Bowtie intake, 3/8 mile tracks where torque is more important than HP. THANKS

i would definitly stick to the 200cc. you will gain more top end with the 220 but you'll lose the all important torque. i run a car and motor similar to you but with a 750cfm motorcraft 2bbl and i run 200cc darts. i did run a set of 180cc iron eagles this year on a 383 and i liked the bottom end a little better.
