a.Stock LT1 castings
b. 2.00/1.56 stainless valves
c. porting
Results: int/exh 269/183 @.500 as flowed by Craig Gallant at GTP.(heads were not ported by GTP, just flowed there)

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.

 

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.

We took it for a test drive. WOW!! <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" /> I need Will's number or email if you have it.

 

Got Wills number and met him. Cool guy!
