I think its a diff. intake due to the larger displacement eng. Just get a fast. Those are good heads though.

You will also need 8 offset rockers, pedestals and LS3/L76 intake.

With the stock cam, ported LS3 heads are overkill.

Looks like it's going to be an azz kicker. Those heads flow like 330 cfm out of the box and thats a nice beefy cam choise. What hp are you expecting? 475-485 would be my guess.
