I have read a lot of posts and it seems everyone has an opinion but no real proof. ...have there ever been any real tests stock or port matched to the larger port heads?

I gave it to a friend for his 318. I think Herb McCandless did a manifold test 30 years ago. I've seen some dyno tests with the LD340, but not the LD4B. Floyd Lippencott IV
