Hey everyone. Brand new to the forums, looking for a bit of help identifying a block and head combo I just bought off a friend for $150. Its a 6.0L Gen IV iron block with aluminum heads. The block has 12576181 stamped on the passenger rear of the block and the heads have a 5364 stamp. I did a bit of research and wanted to verify what I think it is. I think it is a LY6 iron block with L92 aluminum heads, am I correct? Any links, info, or knowledge is greatly appreciated as this is my first V8 build. Thanks in advance.
