What is the difference between the 243 and 317 castings, the way I understood it was that the ls2 got 243 castings but I found some that say they are 317 castings.
Also will the 317's bold direct ally onto a 2001 ls1 block?

317's came on 6.0L engines, they are the same port design as the 243's but the combustion chamber is larger for the 6.0L engine,, yes they can be used on a ls1 but your compression will drop

Ok so I got that, but what about 799 castings I have read that they are the same as the 243's.
Also I read about a center bolt design and a perimeter bolt design how do I know which I have and that I buy the right heads?
My car is a 2001 Camaro that currently has 241 casting heads.
Does anyone know if a set of 799 castings made in 2007 would bolt on correctly?
