Im currently getting a 4age head worked but now Im thinking I should put in a GZE since im spending around the $1500 on the head. If I go ahead with getting the head done it will have big cams,springs,and a heap of other stuff done. Im would like to know what would be the better option. I would like to set the car up for track more then stright line speed.
i would go the 4age, sure the gze may have more power than a standard age, but an age with head work, like you talking about will be better in the higher rev range, which your more than likely going to be in racing around a track....
