Suggestion
The one without the valve cover is risky, since the cam bores are machined as a matched set with the head.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

My son just bought his first Porsche (-99 Vesuvio Convertible 996). It has one cracked cylinder head that needs to be addressed. Lead time for repair from Hoffman is very long so looking into getting a replacement instead. Anybody sitting on a good 4-6 3.4L cylinder head you're willing to part with?
Chiming in to say I'm also looking for a 3.4L cylinder head, but bank 1 (cyl 1-3). Perhaps some lucky member has two good heads they're looking to get rid of!
There’s a few on eBay. Not mine, I know nothing about them. Overpriced IMO for something in unknown condition. The one without the valve cover is risky, since the cam bores are machined as a matched set with the head.

Thanks for pointing those out. I am keeping an eye on ebay but like you stated they are over-priced or sketchy in some other way. I actually bought one from there that was guaranteed to be in good shape only to find that it too had a crack!! May have to bite the bullet and send the current one out for repair instead.
Do you have a part number you need? I have 3 early M96 heads sitting in the shop that are in good shape. If you can use one I would just give it to you.
