The intake ports on the LS6 heads have been opened up substantially. At .650 inch of valve lift, the ports flow 330 cfm at 28 inches of water while volume is 235 cc. This won't do low-end torque production any favors, but a big-bore, (relatively) short-stroke engine like this is all about top-end power--it'll still build enough torque to blow off the tires.
