- replace: I have another head + camshaft assembly that I could swap out from another engine. Do I absolutely need to get the block resurfaced before installing a new head gasket (would be logistically challenging)?
Thoughts?

I'm not a Porsche expert, but I've got some extensive experience with other makes. So bear with me as I try to add something here.
You can sand/ polish the damaged surfaces, but you'll most likely have to take so much material to do it that you'll increase the tolerances dramatically. This would lead to an almost certain failure, as the cam end would oblong that hole in a hurry.
I'd replace it. I've got to think that with the IMS scare on these motors, the must be plenty with bad blocks, but good heads?
Good luck. Keep us posted?
