Casting Numbers? I'm looking to buy some LSA/LS9 heads for my 408 turbo build. Does anyone know the casting number to these heads? Is there a difference between the two and are they in your respective opinions worth it? I'm only trying to make 750-850 rwhp. And I'll be using a 6 speed. Thanks!

from what I can tell they are basically an LS3 head with a slightly thicker deck that when received bare need to be CNC'd to gain over the LS3 head. i read a post where they were supposedly made out of some super space age metal that better helps manage the heat of the supercharged motor.
