Not all the heads were the same Rusty. Not even close. Cam timing was changed as well. So were the intake manifolds. You are arguing against science and the way HP is measured. Stroke doesn’t make HP.
The hell you say. I've torn down so many that were it's pathetic. I have a 400 Ford under the bench that came with the same head castings that the engine in my truck has. I have a 402 right next to it that has the same heads as my friend's 454. I've torn down 350s and 400s with the exact same 442 head castings. SAME. Give it up. You're wrong this time.
