318 Head on a 340 Question

For what little i know I would think if you are running the .444 340 cam you would definately be restricting the air flow at all rpm's. But I'm just an auditor. Pick up a set of 70's 360 heads with the 1.88 intakes. you should be able to find a set for 2 to 3 hundred. I have an extra set of J heads. Where are you located? I think I remember reading in a mopar engine rebuild book that you would smother the engine. YOUR MOPAR BROTHER WALT. :coffee:
