I'm pretty sure they will fit but I don't think the ls2 heads will flow enough for the ls3 block. The ls3 heads flow some big numbers. That's why a lot of guys are upgrading to ls3/l92 heads.

If you are getting a deal on an LS3 shortblock evertyhing will bolt right up. Our cylinder heads flow well enough for the extra 12ci. You will want to find out the cam specs and make sure its good for cathedral port heads if not perfect time to change it . If the combo is right the L92/LS3 heads can be better. You might want to start a thread in one of the technical sections there are people that can help you better than me.

Good luck and welcome!
