the 5.3 will up the CR but one of the vavles is smaller than the ls1.
If you are just going to slap on stock 5.3 or 5.7 then i would not even wast you time doing a swap. If you are going to get ported heads then it does not matter what casting they are they all flow the same if ported the same(853-241).
