243's on stock ls1 motor?
have a set of stock 243's i was thinking of just swaping heads only on my 98 camaro ls1,for now,meanwhile i do cam and my other plans on it.
my question is is the time worth it? rwhp
any downsides of just swaping heads only ? would i need a tune after i swap them?
thanks in advance

About 20 rwhp! Have them ported and do a cam at the same time if you can.

If you put them on "stock" you will notice a difference. They are a big improvement over the stock 98 heads if that's whats on the car now. As far as porting goes- more money more power. Its the name of the game after all. IMO send them out to TEA or AI or WCCH and get them ported if you can. Then tune it 1 time versus 2 if you pull the heads to port them. Either way it needs to be tune if that makes sense.

( technically, the Z06 also has the LS6 block, intake manifold, valley cover and PCV system, and a different PCM calibration )

What I was trying to say, slap on the 243s and the LS6 cam, you will have the 400hp. "LS6" and "LS1" are just engine codes. They are the same bore X stroke,
