Sorry but I don't have a direct answer to your questions. The last cylinder head I removed was long ago for my '70 MBB GT. And to digress slightly more, I removed and replaced that one enough times to have a lifetime of memories :[>
Anyway, you might want to pose this question to the local Parts Shop as they can give you an answer along with the cost of the tools. IMHO it never hurts to have the right tool....
Best of luck!
