1000J engine block VS GPZ1100 crankcase/gear

Just to be 100% sure, its plug and play using 1000J engine block, and "fill it up" with 1100GPZ crankcase and gear, isn't it?

I will use the main bearing cap on crankshaft which belongs to the 1000J block. Since the book says that that part is made specialty according to each engine block.

It is the same crankcase (engine block).
Bolt it in and have fun.
