quick AIR tube header question

My L98 has the AIR pump and AIR tubes on the exhaust manifolds.

Do the LT1/LT4 exhaust manifolds have the same AIR tube provisions?

what I'm getting at is, If I had a free LT4 exhaust, would it bolt up to my L98 with AIR tubes? (some earlier searching says yes it will bolt up to the aluminum heads, but I was unable to find the AIR tube answer...)

Thanks!

Looks like the LT4 removal instructions mention the AIR lines....

The headers should bolt on, and the AIR system should hook up to the backfire valves on the LT-1 tubes. However, there is that pesky EGR problem. (You won't have one)
