Any changes to the head design that could prevent cracked cylinder heads?
 
Finding the answers to these questions may be a guide as to whether to get a new Porsche engine or not.  It may be worth the extra cost if these key problem areas are addressed in the new engine (notice when I say "new" I am not talking about the 987 engine, just the new crate 986 engine).  Of course the Porsche warranty would be nice too.
 
BTW, I am sure the new engine would have the revised RMS seal.
 
Also, another good article on engine failures via autofarm:

I am not aware of any design changes in the new Porsche motors. I know my neighbors 04 went the way of the IMS.
