So I did some research on the heads for all of you wondering if the heads are really from a z06, and I have to apologize that they are actually Ls1 heads. I don't have the contact number or anything from the previous owner to confirm if they really are or maybe he meant that they were ported, but I don't want to sugar coat anything. Although, I can confirm that the engine has an Ls6 intake manifold.
Regardless, I decided to lower my asking price for the price difference of an Ls6 crate engine and Ls1 crate engine according to Hinson's pricing, which is only about a 300-400 difference. My new asking price has been posted up top, again I am sorry for the false advertising and please don't think this is a scam or anything.
Thanks
