Default Ls3 heads on ls2 block.

hey guy's, can you take a look at this pic of the cylinder heads,there are casting numbers you can see. will these work on a ls2 block. there selling for $600.00 for the pair. the pair that you see together are the 5364 casting number, and the other smaller pic is the 0821, is there any difference in these heads? from what i gather these will fit, but i like to get more input from you guy's. i know i will need another intake as well due to the ports being different. in this case i will be going with a magnuson supercharger and cam.

thanks all of you.
