Most heads LS1 heads flow about 300 at .600 lift. those heads dont look bad. If your getting a good deal on them i would go with them

Pay attention to the port velocity guys. Flow numbers are one thing, but they should be in balance with velocity or you'll be losing out.

depends on cam lift.The area under the curve is better on the second set you posted if only using a .550 lift cam.Although with a 4 cfm increase on the same bench for the .100 number I would almost guess they had a slight leak.

Also I think a head that flows more midlift numbers will work better when used with an intake on a car.
