Yeah stock L92s way outflow stock LS6 heads(intake)-around 320 to around 260@600". The midlift numbers are alot higher to.On the exhaust the L92s are about 190 @600' to around 180 for LS6s.No wonder the L92s can make alot of power and with all the intake flow no wonder they like cams with a big split in duration to help get the exhaust out.

Be sure to get the right flow numbers for the right bore size. L92's flow more on the LS3 bore than the LS2. Not a huge difference but easy to achieve with a good ported LS2 head, not to mention the exhaust side of L92's are a bit weak, well that and they are 70cc which means you will need to mill them down to get the compression back and then you have to keep an eye on your PTV. Just looking out.
