    ANOTHER TIP
    I THINK THESE HEADS MAYBE A LITTLE TOO BIG FOR JUST A 496 INCH MOTOR
    BUT MAYBE A 250 SHOT WOULD WAKE THESE HEADS UP AND GET THEM WORKING A LITTLE BETTER
    CANNOT GIVE AWAY SECRETS, BUT THIS MOTOR WILL NOT BE RAN AT THE TRACK TILL 2010.
    WE WILL SEE

    You didn't say what manifold, i don't think the heads are too big, if you have a 454R intake and 2 1/8"/2 1/4" headers, we're pushing close to 750Hp with a pump gas 468" with Brodix 2 extra heads.
    I'm guessing real close to 800 HP. with right tuning, maybe a little more. I'm buliding a 496" for a customer with Dart 308's steel heads and stacks injection, i'm looking to go more than 800 HP with it.
