At 541 cu in, there are other, larger heads available, but yes, Max Wedge ports are a logical choice. TF 240s could be used, that would move the torque peak lower, and limit power output, and I was going to use 240s with a factory block, but it seems like the block demands the Max Wedge heads, but that is as far as I want to go so I can use a 3x2 setup.IMHO the Max Wedge size port is REQUIRED for a 500"+ motor that is intended for big power.
