welcome

Nope sorry man. And the reason why is that the LS1 has round ports for their headers, our LT1 headers have what is called a "D" port, a D shaped port that bolts up. In a nutshell they will not match up so they will not work.

The LS1 Style Headers are spaced different, they are like a big block.
As far as the Ports go.. the LS1 Headers will work on D-ports, I have to use them for my L92 Heads.

It really isn't going to make that much of a difference..shouldn't leak at all either.

Rule of thumb on an LT1. If the headers are D-port use D-port or round port gaskets. If the headers are square port NEVER use anything but square port gaskets or it will leat like hell.
