9961041371R is 2000 boxster S 3.2L head
9961041024R is 2003 boxster S 3.2L head

are these interchangeable? Some say yes and some say no...

what about the 99610492100

On my 2003 the castings are the same, but they are machined differently. The AOS bolts to a boss on the right head, that interface was not machined on the left head. Though I don't recall all of the details there were other differences as well. Gelbster, thanks for the education with the videos. That's what the forum is all about. I'd still pull the plugs first as it can be a positive indication of the failure point.

Agreed -Oh yes - do ALL the simple stuff first . R&R of a cylinder head is something to avoid. Preessure testing as JFP mentioned is also an essential before we go for the dramatic procedures.
