Tapping PCV hole on MP Perf. Valve Covers..

Thanks guys...good ideas. Fishy- I actually ordered an extra set of baffles to under the two extra holes from MP. In the instructions it gives you the part # for baffles and gromets and hardware so I ordered them.

I have dumb question. If you are running the OEM closed air cleaner like Nemo's pic above, and it's vented to the cover. Do you need to knock out the other section for a Holley PCV hose? It's one or the other right? Also, does the passenger side forsure need to be knocked out for a breather?

Thanks again..!

If anyone has more pics of their smallblock with these covers please post them! I'd like to see different set-ups since I'm going to get a new carb too...either Edelbrock or Holley.
