Alternative / Replacement Battery - Late Honda CA77 Dream

[Maximum Carnage]

I'm going to need a replacement battery soon.
I know I can go with the original Yuasa 12-Volt Battery - 12N9-3A, but what other brands work with a 1964 CA77. The Yuasa 12N9-3A has 85 cold cranking amps and I'd prefer one with more CCA. But don't want to fry the old electrical.

What would you advise?

*Feel free to move to electric if it's a better fit.

I have one of these in a CB77.
