Mr. Fixit - Both you and I regretably need to take a second look at these guys for real. Things do change and they are the next generation hot rod standard engine by numbers alone, and that's not just a opinion. For example a complet 6/Liter LS6 motor comes in at a rip roarin' 380 lbs dripping wet, THINK COBRA> On the latest head the combustion chamber design is light years ahead of everyone else for running high compression, on standard unleaded gas too. And as NataSS Inc said the right factory ported head will support supercharged applications, no easy task for sure, in spite of the head bolts. (Studs anyone?)
The only thing I've heard bad about them is if they get hot from overheating they are toast, NADA. Everything warps. Not like a conventional built V8, you can't just let them cool down, then refire them up. I know, I know, I hate progress too. Esp. if they are right, and the horsepower numbers are unreal and backed up.
