In my experience, Cleveland head engines like a lot of initial advance. Boss 302's use 16°. If you are running iron heads you just want to limit the total to less then 36°.

Aluminum heads only need about 32°total but will tolerate 36°.

Most aftermarket cams I've used will only give you around 14 inches of vacuum at idle. Having only 14 is not an indication that something is wrong.
