small base circle is a definate plus, they usually don't cost more, and the larger the cam (lobe lift) after a certain point, (read; LARGE) will also automatically decrease base circle.
but with that said, it depends on other issues as far as cam design (lift/duration,etc.). the cam i used in my 406, a solid roller, small base circle, had clearance at all the normally effected rods, but when i checked close the clearance was not enough. so i still had to clearance the rods slightly, small base circle or not. clearancing the rods is no biggee at all, so dont let that deter you, just be sure to check.
