my buddy runs 15psi from a t25 on a d16a6 with srp pistons and hf mani, its cast i dont think you should worry about it cracking unless your running real lean. heat will cause cracking not psi. it will be more restrictive than equal length though. its made for longevity not horsepower though so you will see gains with an equal length manifold or even a log manifold.
