Why would a cast manifold shrink? I have never heard of that before. Looks like more places for it to leak if you ask me.

How long is a cummins head compared to a miata, and do they naturally run hotter and higher pressure ratios?

I had a Cousin making manifolds for 12V years ago, he had a hell of a time keeping them from cracking all the time.

Default 3 piece manifold?

Inline 6 diesels commonly have 3 piece exhaust manifolds because they are long and there are differing rates of expansion. Some have individual heads for each cylinder even though the block is one piece.
