yes, there are a few:

1) You'll have double the PCV airflow volume, which'll create idle
and low-speed driveability problems due to lean mixture.

2) You won't have proper crankcase breathing unless you also install a
separate breather. This'll create a vacuum in the crankcase, which'll suck
gaskets *into* the crankcase at the valve cover, oil pan, timing cover,
etc.

One PCV valve, one breather, one oil cap (which may do double duty as a
breather or as an attachment point for the PCV valve). All other holes
should be plugged.
