I have a 94 lt1 and im doing a rebuild but i cant find out what cc my aluminum heads are.... any ideas as to how to find out other than that stinkin fluid test method?
what are they stock?

I have no idea... you can usually do a search on a casting number and get this kind of info though...

I'm not an LT1 guy, but I was bored and did a search for you..

Looks like 54cc on the chambers assuming they are stock and haven't been milled..

Some info here:
