[Half-Inch Stud]

Observation: CV-1 Chamber & inlet Bowl-turn is impressive.

YET, SPOTTS had KRE Wide & Tall Port heads all over his shop, and (I forget which one) has a substantially-similar Heart-like Chamber that keeps the Plug dry, and full-daylight wide Intake runner that got me to thinking of the substantive similarity to the CV-1.
================================================== ===============
REMINDER: 95% of the CYL head Performance value is the HALF-INCH before & after the Intake Valve seat.

Hill461 what size valves are you using to get the flow #'s that high?

Not looking for someone with CNC equipment, I was more curious if this program ever took off and if any heads were ACTUALLY produced with the flow numbers as claimed.

Dan Barton did the work he used a 2.230 intake and the stock exhaust valve that comes in the heads. he did a lot of work on the seats and valves and put a wing behind the intake valve he claims is worth several cfm
