head swap ?
how much difference is there between 502 mag heads and hp500s both carb motors looking to sell my 500 heads to a freing but want to make sure there will be a gain for him.

If they are both Gen VI heads, then they should be the same casting (088, I think). The 500 heads will have rocker studs and roller rockers and the 502 Mag heads have a non-adjustble valvetrain with stamped steel rockers.
