I'm gonna be buying 243s off of a guy that just pulled them from a 06 impala ss. Will these work for my ls1 with out machine work? What kind out power can I expect to see unported with a 232/236 .579 112las cam and bbk intake? I did search before I posted and didn't find what I was looking for. Any help would be greatly appreciated.

Heads are heads. The imp still has a 5.3 so it will fit. You'll probably see around 20-30 ish hp
