I'll chime in here just because it sounds like there may be some confusion. First, Doug; you are referring to the vacuum side of the PCV system correct? In other words you're looking for a way to hook up your valve cover mounted PCV to the vacuum of the intake manifold. If this is the case I don't think that we need to be drilling through the intake manifold into the crankcase. If any drilling is needed at all then right under the carb, into the plenum area is more than enough. That being said; this should not be needed either. You also asked about carb spacers; assuming that you have the hood clearance for a spacer under the carb then the spacer is definitely the way to go. You'll gain a little plenum area which will help flow in its own right but you'll also have a very convenient place to hook your PVC up to. That's a win/win in my book and a no brainer. I wouldn't go drilling into the intake w/o knowing exactly what you're doing.

JMHO, Steve
