Battery cables -where does the negative go?

Yes- after 50+ years. Things like oil filters, battery cables etc are changed. But most people are not going to remove one bolt just to move it else where. But I agree- that’s not the spot. My concern is the factory head was not drilled- so now what?
Thanks for your help.

As others have said, it seems acceptable to put it under that front intake bolt, but I like how the one up there ^^^^ is located on the exhaust manifold bolt. Correct? Crapped if I know but it looks much cleaner.
