Have built and tuned a few LS7s and in all respects the ported L92s flow and dyno as well as LS7 heads. Stronger casting and heavier, stronger valves.
Only problem with the L92s is they don't cost enough therefore they don't get get appropriate respect--

Please reword what you're trying to say because I don't understand what you're saying.

Thanks!
We'll see how good of a "tuner" I am since I am doing it myself...

No problem. I did not take it as disrespect.

LS7 CNC ported heads that flow 360 are only $2600 with Titanium valves. I thought that was a good price.
How much are you saving with ported L92. What do the heads cost, how much are you paying to port, are you getting 360cfm, and do they have Ti valves??

The L92s that I have are from Livernois. They cost $1795. They do flow 360 but do not have titanium valves. They use Manley stainless valves. Here is a link to the info on the Livernois site http://www.livernoismotorsports.com/...t.phtml?p=1534
