Arne,

I am in the same situation with my engine and head work. I have a local shop that has worked on Z engines for years. He even has a 78 Z turned into a drag car. I talked to MSA about my head and my engine. What they are probaly going to do is take your head to a local shop that they have a deal with and rebuild it and replace all that is needed. Its getting hard to find some of these parts for these heads and when you do they are costing a bunch due to limited quanities. MSA says exchange only for the E31 but I have a N42 and that is also by Exchange only. I am going to have the machine work done on my head and then assemble it myself with a little help from HLS30.com and a friend of his. Wish you luck.

Arne,

Get in touch with Steve Eperly at Z Therapy in Salem. I'm sure he can solve your problem, or put you in touch with someone who can. He's a great guy, very knowledgeable, honest, and reasonably close to you.

Oops! I guess I never closed this thread out. I ended up buying a parts car instead. The parts car had a complete, sound L24 with E31. Runs pretty good as is. Head rebuild was cancelled.

i thought that was a good deal so i went to their site. i guess that service is NLA
