Re: Flow Numbers....... In stock form, with stock valves, and the factory valve job.... 203-205 peak flow at .450" lift. That's on my SF-600 bench using a radius inlet. Exhaust is 153-156 at .550" lift using a pipe.
And ported LT1 heads that supposedly flow 280+ usually flow mid 250's to low 260's on my bench.

Re: Flow Numbers....... Mine were ported by a gentleman named Will who used to work for Westside Machine in Houston and He flowed my heads on his brand new flow bench. They flowed 276/199 @ .500. They have Ferra 6000 2.00/1.56 valves. I am going to have Craig reflow them just for comparison purposes when I drop off some heads for him to fix up for a blower motor. Either way they should work great on the new motor.
