i think your current cam is to big already. the cams that you posted are very close to the cam in my 414 W8 and there is no way a Trick Flow head will compare to a W8.
While I agree, I do t think he has any illusions of W8 performance. IMO, the search here is for a better cam than he has with taking advantage of the ports capabilities. Once the overlap and power band are found for his combination he’ll be in good shape.
