If you could only have too much or too little valve area which would you prefer for making power and what's the maximum percent of too big or too small?

If it's a racing application, I would always rather be too big.
If you're too big, you will lose some torque, but there's things you can do with the cam profiles, to get back the torque.
If you're too small, you lose Top-end power, and there's nothing you can do, to get that back.

I have no idea, about max %. It's not something I would ever want to calculate. If it's wrong, fix it.

What if i have an engine that requires 3.065 and the after market head is 3.676? Is that too much to fix with a cam?

Depends on the application.
25 years ago, the -12 Brodix heads they ran on the 410" sprint cars, were way too big for the engines, but they worked fine in the application.
