Just wanted to let you guys know about a interesting topic going on over at the Corvette Forum about the wrong heads being put on some of the later 2007 vettes. The LS2 heads wich is the same as the LS6 head has a casting number of 243. Problem is that some of the LS2 have heads with a casting number "799" truck heads, wrong head!!!
I have checked mine and it has the 243 castings.
A vette owner dynoed his vette with some mods and only pulled 345!!!
So far 5 07 vettes have this head
If you have this issue chime in.
