0.150 88.5 112.7
0.200 112.4 152.5
0.250 145.2 185.7
0.300 167.7 213.8
0.350 183.2 233.5
0.400 195.2 255.0
0.450 204.7 266.4

i was guessing they were ls1 cores cause of the flow #'s then the exhaust port's i hope you are happy they look really nice...i bet you can't wait to slap em on and see how they perform

Sorry JRP, my digital camera sucks (it's about 8 years old) - that's about as closeup as I can get. 
I keep spending my money on go-fast parts instead of a new camera.
Thanks guys !

The flow #s are from the flow sheets, the valve sizes/port sizes I got from their website :
