Couldnt find answer to 6.0 heads question
 

All I want to know is if the 6.0 heads directly replace the stock 5.7 LS1 heads? Will anything else need to be replaced, i.e. pushrods? How much will they lower the compression ratio?

Thanks for any input. :usa:

i know for a fact i answered this exact question only a few weeks ago ;)

all gen 3 heads are interchangible, they all have the same deck thickness. only difference is combustion chamber and valve sizes (5.3 smaller intake). box stock 6.0 heads with a .052 gasket will put you @ 9.79 CR.

ya know I dreaded getting that response :lol:

I must suck at searching

thanks for the info by the way :)

I need to get my hands on a set of 317 also. Guess i have to sell my LS6 heads. I am going with a turbo set up also witch kit are u getting.

Im doing a custom setup with the help of some of my knowledgable buddies. To me, the kits were a little too pricey...in the end it may end up costing me the same with the addition of more headaches, but it will be fun :burn:
