Did the 04 ls1 come with 243 heads?
Just as they title says also did ls2 have the yellow valve springs like the ls6? Trying to figure out if my t/a has a ls2 or not. It has 243 heads and they don't appear to have been removed. Not sure what else to look for to see if it's actually a ls2. Is there any markings on the block? It made just over 330rwhp my tuner said that could be right for a ls2 considering its an a4 and the y pipe is trash on it. Any inputs?

That's about right stock RWHP for an Auto LS2, but the LS1 from 2001 to 2004 came with 241 heads (Some 200's had 241's also.) If Im not mistaken no ls1's came factory with 243's. The 243's on the LS2 did not have the sodium valves like the LS6 cars did I dunno about the springs.

LS1's dyno between 280-300 stock, 332 out of an auto I don't think anything was "Up" the car ran decent at the track, was normal for a bone stock auto GTO. Im just saying it's not out of the question that op's car has an LS2. There's no telling

What casting numbers? On the block? My tuners dyno usually reads low my full bolt on 02 a4 ta made 317rwhp but with stock suspension and 2800 stall ran 12.40s. I'm trying to find a way to see if it's a ls2 cause I want to do a heads and cam and if it's a ls2 I can put on bigger heads lol. So would there be something on the block that would say? The heads to me don't look like they have ever been removed but I can't say that 100%

Normally LS1's are between 280-300. Anything over 300 is not the norm from what I have seen. Where are you seeing them up to 330???

I wasn't trying to say the dyno was the end all be all. Also not trying to argue, just saying that is within the realm of a normal LS2 dyno #, especially if the OP has stock exhaust and an A4 car like he says.
