      GMPP BBC valve covers

      I have a set of the GMPP valve covers for a big block chevy. I need to drill them for pcv and breather. They are both 3/4". There are no baffles in the valve covers. Can I just use baffled grommets? I don't really want oil mist all over the place. Thanks

      That is exactly what I did. No issues so far, though the engine has run for less than 3 hours so far with no sirited driving.

      Good Luck.

      The baffled grommets work fine
