Not entirely.
I had a 2001 Camaro SS that I was damn near POSITIVE was an 1168 LS6 block.
That wasn't the case. I had no bullseye, and no ribs inside the block under the valley cover. Didn't have to cut for the LS6 valley either. I've got the casting # wrote down at home, but it wasn't an 1168 block.

My 2002 Firehawk has no bullseye but 241 heads. Does this mean I'll see much improvement if I swap to LS6 243 heads? I already have a 224 cam and the car put down 408/396 at Vengance racing

Ws6 in 2000 came with the older ls6 .. i made a very good living building ls motors for hot rods .. you know it all d.*** should get a life .stop being you tube mechanic.. go build something . 241 heads till the 243 799 came out is what they used .

First, the Gen III LS6 engine didn't even exist in any production vehicle for model year 2000, it was released for 2001 Z06 Corvette and it never appeared in ANY F-body from the factory; not WS6, SS or even Firehawk.
Second, it's entirely possible that you've seen 2000 model year LS1s with 241 heads, but that does NOT mean they are LS6s as this was NOT an LS6 specific head. 241 was an LS1 head that appeared on some very late 2000 models and for all 2001-'02 model LS1s. And 241 heads were not the original castings for an LS1, prior to these GM used 853s and 806s.
All LS1s have made 345hp or better since 1997. It's been well proven through many dyno tests that GM was simply playing a marketing game with the power ratings between C5 and F-body. ~350hp is a typical "net" dyno number for flywheel HP, but "gross" tests have been done that put a stock LS1 at over 400hp for sure.

I know that my car doesn't have a an LS6 like from the ZO6. But it does have an LS6 in it. It's a 454 LS6 like they use in Chevelles. No word on power rating but I have to think that the ram air is worth a few more ponies than a cowl induction so I'm saying somewhere a little north of 450. And since Pontiac wanted these cars to handle it's a super rare aluminum block. The guy I bought it off told me all about it. He said he bought it new and it was over $50K. It's low miles and super clean so I think it was a bargain for me when I bought it for $38K. Pretty sure it's one of one.

If you can open the hood you can tell in 3 seconds. See if there is a BULLSEYE mark on the flat area just in front of the passengers side head. If there is then its a LS1 if not then its a LS6. I KNOW everybody will say oh you have to check the block code wah wah wah....BUT I would like someone to show me a LS1 block without a bullseye and/or a LS6 block with one. So lets say that way of checking is 99% accurate and takes 5 sec without carrying it to GM.
Heres a pic of the bullseye:

Based on the aluminum block, I think it's more likely that you have a '69 ZL1 engine. GM had one of these engines still left over as NOS inventory as late as 2002, and I recall reading somewhere that the decision was made to install it in one of the late 4th gen f-bodies - but only one example was ever fitted with this engine from the factory, and you seem to be the owner of said vehicle. You have a rare bird indeed, I'd value it north of 6-figures even in poor condition; if it's really nice and mostly original, then you could probably set a new high record at Barrett-Jackson.
