im sure someone will correct me if im not completly right, but the rectangular ls3 ports are rather lazy and dont like huge cams, they make much more power with a somewhat smaller cam, that may be the reason most of us dont know, because they arent used in our motors often as they make less power.

why would you have to pull the heads? install the cam, try to turn the motor over with a wrench on the balancer bolt, if it stops at any point you know it wont fit, right?
