No. Two totally different platforms.

^^ Nice response.

No, they will not. If you want a nice set of heads look into Lloyd Elliott.

You can use the I/E valves from the LS1(a little bigger and alot lighter)

I talked to lloyd on this awhile back. He said people do, and sometimes it works out great. But new guides are needed because they are smaller stem.

Yea, I have heard the Valves are interchangeable as well.

The Heads will not bolt up- different Bolt Pattern, and Rocker Geometry, as well as Coolant Passages.

Some people have been running LS1 Rockers in LT1's..I guess it works out in some cases.

Yes, you can. You'll need to install 8mm guides in your heads and use a LS1 spring kit. I made a thread about it a long time ago:

I also covered it in my 93 thread:

Another thing I typed up about this:

I know I typed something else about this, but I can't find it right now.

so thats a no on the heads but i can use the lifters? i guess it would be worth it to just get some better after market ones?

i am only asking about the heads because my friend is insisting that he has ls1 heads in his 95 camaro with a lt1 block. he bought the engine already assembled so i guess he got tricked.

lol Yep, I'd HAVE to see an LTS1 engine! If you REALLY want to catch him lying, ask him if he kept the LT1 intake or modded the LS1 intake to fit.s Say it just like that, even though if he had the LS heads, the intake would be the least of your worries. Actually IF he somehow magically managed putting on those heads, then the LT1 intake wouldn't even work THAT is how you'll catch him

To better explain why...
GEN I and II small blocks look like this
Intake.... .[][]..[][].
Exhaust.. []..[][]..[]

GEN III/IV (and most likely for quite a long time to come)
Intake.... [].[].[].[]
Exhaust.. .[].[].[].[]

Here's a good pic of a set of LSX Heads for you to see what they look like.
Most are Cathedral Port, these are the L92/LS3 Heads..
