yes they can. down here in AUSTRALIA i have STOCK LS6 heads on my LS1.
CAM ONLY. it makes 296rwkw and the car runs consistant 11.50s@119mph full weight. 1650kg.
Switching to those heads you will need new valve center bolt valve covers and the coil brackets for 99 and up heads. I have yet to figure out if if the bolts that hold the 98 coils to the heads will be reused to old the coils to the bracket. I know you will also need the bolts to hold the coil bracket to the cover but im gonna say had fairly easy from any place that sells bolts. or just order them from gm and wait the 4 days for shipping lol.

motors are the same other than the heads. they are factory LS1/LS6 and carried over on to the LS2. all i have done in a sence is make my motor a LS6 with a cam only.
they are a standard GM head that was made for the LS1. then they called it a LS6.
yes these heads give a little bit more performance but they are standard fittment on the LS6 which is a LS1 with better design heads.
you guys should know that.

i didnt post to start a war. only posted to let the guy know that yes you can bolt these heads straight on and yes you get good results from the new GM design LS1/LS6 heads.
AS of 2002 onwards all LS1 motors came with LS6 manifold and injectors as standard equipment. what would that make the motor then? LS1 or LS6.

no thats not the case at all. the LS6 is the high performance version of the LS1.

well this can be debateable, since these heads are a direct replacement from a dealer were as AFR,Trick Flow,ETPs, and any other head that is ported polished and fitted with bigger valves are not. So if one has a engine replacement from a LS1 to a LS6 they have a H/C engine?
It's not debatable. They didn't come on the car. He changed the heads and cam so he could have more power. Thats a heads/cam swap. How do you debate that.
If he had gone from the older casting LS1 heads to the newer ones. It would still be the same deal, but not worth mentioning. Since they don't really add any power.

as i said. from 2002 up all LS1 motors came with LS6 manifold and injectors.
LS1 or LS6?. So all these guys out there that have a early LS1 with a cam only then put on a LS6 MANIFOLD cant claim cam only because its cam and manifold?
what rubbish. the LS1 and the LS6 are the same engine. the LS6 has better flowing non ported totally stock heads. if you had a stock LS1 and put a LS6 manifold on would you still say its stock? YES you would. WHY? because it being a LS1 comes standard with that manifold from 2002. the gains you get mean nothing. you would still say it was stock. my motor is cam only. it has no head work at all. heads are stock from GM as fitted to the LS1/LS6 BLOCK.
I would tell someone who didn't know LS1s that it was stock, but I myself would know better. If you tell someone that you are cam only thats one thing, but if you believe it yourself you're and idiot. Also the LS6 block is different.
Lets do it this way, Say you have an older LS1 and you put LS6 intake, heads and cam. You would still say that you were stock? Even though you'd be making about 40 more hp and you were obviously not stock.
Or if I had an LS2 but I put an LS7 top end on it. Still stock?

you tell me what is different about a LS6 BLOCK to a LS1 BLOCK.?
As for a LS2 and a LS7 the LS2 didnt come with LS7 heads. they are different
http://www.corvetteactioncenter.com/...06/ls1ls6.html
check the link and you tell me what is different.?
i can tell you what it is. its compression. why. because it has a free flowing, better design stock head.
a LS6 is a LS1 with a better design manifold and heads. still stock from GM. NO PORTING OR POLISHING. NO BIG VALVES. JUST A MORE FLOWING STANDARD HEAD.
does that make a LS2 a modded engine. it has 243/LS6/LS1 heads on it.
the thing is they are standard on the LS2 and also on the LS1/LS6.
As for the LS1 with manifold, heads and cam if they are aftermarket heads or modifyed 241 cast and the cam is aftermarket then its heads and cam. power to be made.
but if stock 241 and stock cam then the engine is stock.
when you tune your car you make more power. engine untouched. is that stock?
but i bet you tell people it is but it has a tune.
