Is More Flow Better, Is The Smallest Intake Port That Flows The Most The Best

That head is too small for 340 inches turning 8500.

Dan might disagree with you considering he's managed 7800 with just a ported 587 head @ 410 cubes. Do you think the CSA of his heads would be bigger than a ported W2?

8000 rpm not a problem at all either, especially with a small block. try to get the intake valve 110 grams or less, Use a hollow lifter, [not the solid chunk of iron lifters], Mopar perf. lifters are hollow. 5/16" .08 wall pushrods. 150#/160# seat and 380#/410# over the nose held in place with 10* tit. retainers. If it is in your budget, put titanium intake valves and lighten the exh valves to less than 90 grams and you can reduce the springs to 130# seat and 350# open. My demon is set up with tit. intakes. With 4.88 gear I went through at 7800rpm. Have 4.56 gear now and only sees 7400rpm but slowed aprox. .05
