    I'm putting a 231 intake on my 225 and am at the point of plumbing things. The 225 just had a PCV valve on the passenger's side valve cover. The 231 intake has a PCV valve aft of the carb.

    What are people thoughts on blocking off one? Which one?

    Thanks!

    Shouldn't really matter, as long as you have the PCV valve hooked up to manifold vacuum and a breather on one of the valve covers.

    I hope your following the prescribed work on the heads in this swap. There can be some passages that do not line up with a 225 block and 231 heads. Pat Ganahl's V6 Performance book can lay this all out for you if your not already there.
