Flow numbers would certainly increase but why advertise "street" heads that flow 400 CFM at .900 lift when no one is really going to drive their Pro Stocker back and forth to work.

I'm sure we'll do more testing at higher lifts once the CNC ported versions are out. We just wanted to show how these as cast stack up against comparable street heads.

Thanks for asking Stan.

Again thanks for the response.

Yes this is the street section, but the other section here is race. So there a number of people who full in between. Let call them street/strip cars. I would have thought some of these people might have been interested in the flow @ 0.700" lift.

We'll get there and I appreciate hearing from guys like you. If no one tells us what's important to them we have no way of knowing and if one is asking possibly hundreds are wondering. Thanks for letting me know.

I for one would be interested in flow numbers up to .700" We run our street cars with over .600" rollers in them and drive them everywhere so I'd be particularly interested in .050" increments above that, and see if there is a point where the heads roll over.

Same, I'm at 0.630" after lash in my street(95%)/strip(5%) car. Capping lift to well under 0.600" may have been the practice back in the day with factory iron heads, not anymore.
