What do bone stock LS1 heads typically flow?

Also, what are some of your numbers on people that have had ported heads. My valves I'm putting in my heads are 2.02 and 1.65. They're gonna be fully ported. The porter said they will flow about 275 intake and 205-210 exhaust. What do you guys typically see?
Thanks

 

I would also like the flow numbers for stock LS1 heads

275 sounds kinda low for LS1 heads. I know i can get LT1 heads ported to flow damn near 275 for only about $800 fully assembled. Good LS1 heads usually flow close to 300 cfm.

LS1 Stockers flow about 230-240. LS6 heads flow about 250-260.

Take a look at this....

$1600 for 300+ cfm heads.

 

I have the numbers for stock 99 heads, I am out of town right now so I'll post them when I get back (prob a week though but I got the chart)

 

Here is a chart showing the stock vs good ported heads (on a '99)

Intake

lift Before After Gain
100 65 74 9
200 129 161 32
300 191 229 38
400 223 261 38
500 231 294 63
600 229 306 77
700 227 310 83

Exhaust

100 53 61 8
200 101 115 14
300 135 163 28
400 165 191 26
500 179 212 33
600 185 225 40
700 187 232 45

 

is the 1.65 for the exhaust valve a typo? the largest I have seen is a 1.60.

the flow numbers on our stage 1 heads are like this
Flow numbers are
Lift Intake Exhaust
.200 153 118
.300 212 166
.400 243 183
.500 281 212
.600 293 221

using a 2.02 and a 1.57 valve
