Does Any Body Know If You Can Put 07 Z06 Manifolds On A 02 Ls1 Z06 Motor?

The '02 ZO6 has a LS6 engine..with "D" port holes...the LS7 has round port I don't believe they will fit.. put a set of LS7 oyLS2 engine and gained 7HP.

Yes they can and I run them and have proven results! I

I did a write-up on the whole set-up!

I used the C6 Z06/ZR1 gaskets, don't let anyone tell you different, they will be lying. A few people went with LS1/6 gaskets and pulled them off in favor of the C6 ones made for the manifolds!

I got all my gaskets here:

Here is my write-up with all the part numbers:

Thanks,Matt

This information is not correct on the LS7 exhaust - too bad you didn't gain more!

I'm in the process of starting this install on my '02 C5 with Matt's help. His write-up is excellent - take a look and study his performance results.

If the LS7 manifolds fit on your LS2, why wouldn't they fit on an LS6? The LS2 has the exact same cylinder head castings as the LS6.
