A regular SBC timing cover will not work on an LT1.

are the timing chains the same?

Stock to stock, they are not the same timing sets. I have never checked, but just the chains might interchange. The cam gear is the biggest difference, because it has extra teeth on the back to drive the water pump drive gear.

A regular SBC timing set can be used on the LT1 only if an electric water pump is used to eliminate the need for the water pump drive gear.
