Default Quick question on LS3

I noticed that the LS3 shares the same head design as the Ls7 and l92. I suppose this means that my AFRs won't fit huh?

The LS3 heads and L92 heads are the same. AFR heads will fit on the block, you'll just have to switch to something like a FAST intake.

unless you've got a block that's 4.00" or larger, you can't use them anyways.

I think hes asking if he can use his AFR heads and Fast manifold on an LS3 block.
