I believe TL-S/CL-S head swaps have been performed on the J30A1.

remember, you have a new 7th gen's J30A2 which is different than the 6th gen's J30A1, so I doubt you would want to pull stuff from the current Acura J32A2.

I think your source for parts would come from the next gen CL-S/TL-S just like it was for our 6th gens with the current CL-S/TL-S?

BTW, check out helminc.com for service manuals.
