Aha! 5 base gaskets works.
I asked here when the question belong to a turbo compression build, but also my future project using CB900 DOHC rods that fits a CB750.  They are 1.5mm longer.... 1-2 mm copper base gasket will fix that. Cheap rod upgrade.

any chance of dyno runs though out the process to see gains and help with tuning?

Possibly. I guess a pre-turbo dyno run to establish a baseline would be a good idea. I will see if I can find a local shop that can do this.
